Question

Given that the number 33,554,432 is equal to 2^25 , explain how you know that 33,554,432 is not a square number

Answer 1

First of all, perfect squares do not end in 2.

The exponent has to be an even number when 2 is the base. For example 2^8 = 64. 8 is an even number. So 64 is a square number.
