4 add 12 = 16 and that is an square number
25 25 is not even and is a square. 3 is not even or a square.
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).
It is an even number.
Yes. One has to be the square of an odd number. The other square has to the the square of the even number either before or after the odd number. If this is confusing just plug in real values. In either case, an odd times and odd is odd. Therefore one of the squares has to be odd. AN even times an even, however, is always even. Therefore, the second square has to be even. Thus, one of the squares is even and the other is odd. An even plus and odd is always odd.
An even number.

Yes, an even number plus an even number is always even. Also, and odd number plus an odd number is always even.
The square of an even number is always even.
Any even number you square will give you a even square number =)

An even number is any integer that can be divided by two evenly. A square number is any integer multiplied by itself. 2 is even 3 is odd 4 is even and a square of 2 9 is odd and a square of 3 The square of any even number will itself be an even number, and the square of any odd number will itself be an odd number.
An odd number plus an even number will always be an odd number.
Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.
An even number.
No, never is.
