## NCERT Solutions for Class 7 Maths Chapter 13 Exponents And Powers In Hindi PDF Download

Chapter 1 – Integers

Real numbers are necessarily represented on the number line. Move right to add positive integers and left to add negative numbers. Subtract a positive integer to move left, and a negative number to move right. In this chapter, students will learn how to apply these facts to their daily lives.

Chapter 2 – Fractions and Decimals

Chapter 2 of Class 7 Mathematics covers decimals and fractions and how to add and subtract them. If students need to multiply decimals as integers, they must learn how to multiply decimals. Then count the number of digits to the right of the decimal point in both decimals, add both counted digits, count the digits, and set the decimal point. From the entire right digit of the product. It is important to note that the count must include digits from both digits. Students will also learn how to multiply and divide decimals and fractions. There is a way to multiply fractions by multiplying the numerator and denominator separately. This chapter will also show students how to flip a fraction to get the reciprocal. This is an important concept that is also used in the Simple Equations chapter. Students can download the study material for Chapter 13 in the form of NCERT Solutions Class 7 Maths Chapter 13 In Hindi.

Chapter 3 – Data Handling

This chapter describes data collection, recording, and presentation. Before collecting data, it is important to ask if the collected data should be tabulated so that it is easy to understand and interpret. There are questions based on probabilities that describe real-world situations that are certain to occur, some of which may occur, some of which may not, and some of which are impossible. Students can also, refer to NCERT Solutions Class 7 Maths Chapter 13 In Hindi for solutions to Chapter 13.

Chapter 4 – Simple Equations

This chapter describes working with conditional equations on a single variable. Both expressions should have the same value. It also shows the values ​​of the variables that satisfy the equation, known as the solution of the equation. It is well known that swapping the right and left sides of an equation does not change the equation. This property should be used to solve the equation. Transposing a number has the same effect as subtracting or adding the same number from both sides of the equation. This chapter describes how to create simple algebraic expressions that correspond to real solutions. To create equations that help solve them, students need to use techniques that perform mathematical operations on both sides.

Chapter 5 – Lines and Angles

A line is a line with two endpoints. A type of line with only one endpoint is known as a ray. Students should have already learned that lines do not have endpoints. In this chapter, supplementary angles (angles that sum to 180°), adjacent angles (angles that share a common vertex), linear pairs, perpendicularly diagonal angles ( Two pairs of diagonals), etc., have been discussed. Two lines intersect at a point called the point of intersection, and when they do not meet they are called parallel lines no matter how far apart they are. Students will also learn about horizontal lines, which are lines that intersect multiple lines at a particular point. These concepts are used in the chapter on Triangles and their properties.

Chapter 6 – Triangles and Their Properties

This chapter describes the elements of a Triangle, its three sides and its three angles. Students will also learn the 3 altitudes and 3 medians of the Triangle. Students should know that the exterior angle of a Triangle is formed by lengthening one of the sides of the Triangle. An exterior angle is formed in two ways. A Triangle’s exterior angle measurement is the sum of its opposite interior angles, and the angle sum property of a Triangle implies that in a Triangle, the sum of all three angles is 180°. Students will also learn Equilateral Triangles (Triangles with all 60° angles), Isosceles Triangles (Triangles with two equal sides) and Right angled Triangles (Triangles with one 90° angle). Students ought to use the Triangle side length property to quickly solve a variety of problems. This chapter also introduces the Pythagorean theorem, which is used in other classes.

Chapter 7 – Congruence of Triangles

In this chapter, students will learn about Triangle congruence and its theorems. For the congruence of two Triangles, students should pay attention to the four main rules: SSS, ASA, SAS, and RHS rules of congruence. where S represents the side of the Triangle and A represents the angle. Note that triangles have no AAA congruence. Understanding these concepts will help students solve geometric problems in higher grades.

Chapter 8 – Comparing Quantities

Comparing quantities involves finding relative relationships between quantities. These quantities are weight, height, grade, salary, and so on. To compare these quantities, students need to convert them to fractions. If the fractions are equal, the two ratios are also equal. That is, the four quantities are proportional. Students can also compare quantities as percentages. The numerator of a fraction with 100 as the denominator is known as a Percentage. They are commonly used in everyday life.

Chapter 9 – Rational Numbers

Students must have learned about rational numbers in a previous class.  A number which can be represented in the form of p/q is known as a rational number. where q is nonzero and p and q are integers. Examples of rational numbers are ½, 7/2, and ⅖. All fractions and integers are rational numbers. This chapter contains many exercises to help Students become familiar with rational numbers. A positive rational number is a rational number with positive integers as the numerator and denominator. A negative rational number is a rational number whose numerator or denominator is negative. The number 0 is not a positive or negative rational number. In this chapter, students will also learn how to add, subtract, multiply, and divide rational numbers by adjusting the standard form of rational numbers, the numerators, and denominators.

Chapter 10 – Practical Geometry

In this chapter, students will look at different ways to create shapes using compasses and rulers. Concepts from the Congruence of Triangles chapter are used to draw diagrams of triangles. When plotting given a line and no points on it, draw parallel lines using the “isometric” concept of horizontal graphs. Students can also use the “equals corresponding angles” idea in construction. This chapter also uses knowledge of properties of Congruent Triangles such as SSS, SAS, ASA, and RHS.

Chapter 11-Perimeter and Area

This chapter describes measuring 2D geometry. The area is the portion of the plane occupied by a closed figure, and the perimeter is the distance around it. In this chapter, students will learn to calculate the volume of various objects in daily life. To calculate the perimeter or area, students would use various formulas, such as:

Perimeter of rectangle = 2 * (length + width)

Area of ​​rectangle = length x breadth

Perimeter of square = Four(4) × sides

Area of ​​square = side x side

Students will use the unit conversions they learned in the previous class. Students can use area units such as 1 hectare = 10000 square kilometres, 1 square centimetre = 100 square millimetres, and 1 square kilometre = 10000 square centimetres.

Chapter 12 – Algebraic Expressions

In this chapter, students will learn how to create algebraic expressions using variables and constants. Learn how to use operations such as addition, subtraction, multiplication, and division with constants and variables to create expressions. Polynomial has more than one term. Polynomials include binomials, trinomials, and so on. Terms with the same algebraic factor are called terms, and terms with different algebraic factors are called different terms.

Chapter 13 – Exponents and Powers

Large numbers can be difficult to read, process, understand, and compare. Exponents and powers make things a little easier. Exponents are used to convert large numbers to their short form. Focus on this chapter, as it will be veryhelpful in future lessons. Numbers in exponential form follow certain inherent laws. The only way to fully understand these laws is to practise them. All the solutions of this chapter are available in the form of NCERT Solutions Class 7 Maths Chapter 13 In Hindi

Chapter 14 – Symmetry

A figure is symmetrical if it can be folded along a line so that both parts are coincident. Students know that the angles and sides of a regular polygon are equal. This means that there are multiple lines of symmetry. Mirroring leads to symmetry. In other words, students need to pay attention to the left and right orientations. Students can also find the angle or rotation, and learn to turn objects right or left. If an object looks exactly the same after rotation, it must be rotationally symmetrical. This is an important concept as it can be used in  everyday life and offers beautiful designs.

Chapter 15 – Visualising Solid Shapes

Examples of plane figures are Squares, Rectangles, Circles, Triangles, and Rectangles. Similarly, there are examples of solid shapes such as Cubes, Spheres, Cuboids, Cones, Cylinders, and Pyramids. In this chapter, students will learn about the sketches and forms of these figures. The corners of a solid are called vertices, the flat faces are called faces, and the line segments are called edges.
