When a number is even is the root even too?
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).

Yes. And this means that any even perfect square is always a multiple of 4 - not just 2.
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 can you tell if a number is a perfect square?
One way is to get the prime factorization of the number. If every prime occurs an even number of times, it is a square, otherwise, not. Another is to estimate the square root of the number, and square it. If you get more than the number, try a lower estimate; if less, a higher one. Using interval bisection you very quickly zero in on the square root, if it is a whole number. If so, the number is a perfect square. Otherwise, you find 2 consecutive whole numbers between which is the square root, in which case it is not a perfect square.
When a number is even is the root even too?
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).
