Question

two perfect square numbers between 60 and 90

Answer 1

8*8=64 and9*9=81 are the two square no. between 60and 90

Answer 2

Two perfect square numbers between 60 and 90 are 8*8 = 64 and 9*9 = 81.

A perfect square or a square number in mathematics is obtained by multiplying a number with that number itself.

We have to find two numbers which are perfect squares of a and b such that a*a and b*b lies between 60 and 90

The perfect square right before 60 is 49 = 7*7

Therefore, the next perfect square would be 8*8 = 64

The perfect square after 64 would be 9*9 = 81

Also, 60 < 64,81 < 90

Thus, the required perfect squares are 8*8 = 64 and 9*9 = 81.
