All numbers have square roots. You may have meant which factors of 40 are perfect squares. That's 1 and 4.

Find square root of a number?

first, you take a number. for my example, I'll use 12. 12x12= 144. 144 would be the square number, and 12 would be the square root. clarification: if you multiply a number by itself, the product isn't the square root, the factor is. and if your really stupid, here's this: 12x12=144 F F P F means factor P means product. happy now?

Is there a prime factor greater than the square root of an integer?

No there is not. If you are looking for prime factors of a number and you get to the square root of that number you can stop. Yes, there is. If an integer is not itself a prime, then one of its factors will be less or equal to its square root and the "co-factor" will be greater than or equal to the square root. But both cannot be greater than the square root so, when searching for factors, you can stop when you reach the square root.

Does there exist an irrational number such that its square root is rational?

No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
