Q.1 Find the square of the following numbers.

(i) 32 (ii) 35 (iii) 86 (iv) 93 (v) 71 (vi) 46

Ans

i 322=(30 + 2)2=(30 + 2)(30 + 2)=30(30 + 2)+2(30 + 2)=30×30+2×30+2×30+ 2×2=900+120+4= 1024ii352=(30+5)2=(30+5)(30+5)=30(30+5)+5(30+5)=30×30+5×30+5×30+ 5×5=900+150+150+25= 1225

(iii) 862=(80+6)2=(80+6)(80+6)=80(80+6)+6(80+6)=80×80+6×80+6×80+ 6×6=6400+480+480+36=7396 (iv) 932=(90+3)2=(90+3)(90+3)=90(90+3)+3(90+3)=90×90+3×90+3×90+3×3=8100+270+270+9=8649(v) 712 =(70+1)2=(70+1)(70+1)=70(70+1)+1(70+1)=70×70+1×70+1×70+1×1=4900+70+70+1=5041

(vi) 462=(40+6)2=(40+6)(40+6)=40(40+6)+6(40+6)=40×40+6×40+6×40+6×6=1600+240+240+36= 2116

Q.2 Write a Pythagorean triplet whose one member is

(i) 6 (ii) 14 (iii) 16 (iv) 18

Ans

For any natural number m>1,2m,m21,m2+1 forms a Pythagorean triplet.(i) If we take m2+ 1=6, then m2= 5The value of m will not be an integer.

If we take m21=6, then m2=7Again the value of m is not an integer.So, we try to take m2 + 1 = 6.Again m2 = 5 will not give an integer value for m.Let 2m=6m=3Therefore, the Pythagorean triplets are 2×3, 321, 32+1 or 6, 8, and 10.

(ii) If we take m2+1=14, then m2= 13The value of m will not be an integer.If we take m21=14, then m2=15.Again the value of m is not an integer.Let 2m= 14m= 7Thus,m21=49 1 = 48 and m2+ 1=49+1=50Therefore, the required triplet is 14, 48, and 50.

(iii) If we take m2+1=16, then m2=15The value of m will not be an integer.If we take m21=16, then m2=17Again the value of m is not an integer.Let 2m=16m=8Thus,m21=641=63 and m2+1=64 +1=65Therefore, the Pythagorean triplet is 16, 63, and 65.

(iv) If we take m2+1=18,m2=17The value of m will not be an integer.If we take m21=18, then m2=19Again the value of m  is not an integer.Let 2m=18m=9Thus,m21=811=80 and m2+1=81+1=82Therefore, the Pythagorean triplet is 18, 80, and 82.
