The square root of an even number can be an even number (if it is a perfect square), or an irrational number (if it is not).
Is the square root of an even perfect square is always an even number?
Yes. And this means that any even perfect square is always a multiple of 4 - not just 2.
Is perfect squares only even numbers?
No, perfect squares are not only even numbers. While the square of an even number is always even, the square of an odd number is always odd. Therefore, perfect squares can be both even and odd, depending on whether the original number being squared is even or odd. For example, (4) (from (2^2)) is even, while (9) (from (3^2)) is odd.
Is the square root of 3 a rational number?
No. 3 is not a perfect square, so its square root is irrational.
What is an even sided shape?

How would you know if a number is a perfect square by just looking at the exponents in its prime factor?
A number is a perfect square if all the exponents in its prime factorization are even. For example, if a number can be expressed as ( p_1^{e_1} \times p_2^{e_2} \times \ldots \times p_n^{e_n} ), where ( p_i ) are prime factors and ( e_i ) their respective exponents, then it is a perfect square if ( e_1, e_2, \ldots, e_n ) are all even numbers. If any exponent is odd, the number is not a perfect square.
