Surds
If‘a’ be a rational number, ‘n’ be any positive integer and ‘nth’ root of ‘a’ is an irrational number, then ‘nth’ root of ‘a’ is called a surd or a radical of order ‘n’.
Rationalisation means converting the denominator of a given number to a rational number by a suitable multiplication in its numerator and denominator.
If the product of two irrational numbers is rational, then each one is called the rationalising factor of the other.
