Question

Using the prime factorisation method, find which of the following numbers not

perfect squares are.

(i) 768

(ii) 1296​

Answer 1

Answer:

1296 is a perfect square!

Because,

If a number has to be perfect square, then it has to be a power of 2 or the power has to be any even number

798 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

= 2^8 x 3

Hence, it's not a perfect square!

1296 = 2 x 2 x 2 x 2 x 3 x 3 x 3 x 3

= 2⁴ x 3⁴

Hence, it's a perfect square!
