Question

the square of an even number is odd or even
​

Answer 1

Answer:

Squares of even numbers are even (and in fact divisible by 4), since (2n)2 = 4n2. Squares of odd numbers are odd, since (2n + 1)2 = 4(n2 + n) + 1. It follows that square roots of even square numbers are even, and square roots of odd square numbers are odd.
