Best Answer

Every number has two square roots ... a positive one and a negative one.

Example:

+2 and -2 are both square roots of 4, because when you

multiply either of them by itself, the answer is 4.

The positive square root of a number is the square root that's not negative.

The non-negative square root of a number is the positive one.

3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.

No - a natural number is a whole number. Therefore, the square root of 49 is a natural number, but the square root of 50 is not.

The square root of 51 is an irrational number and it is about 7.14128429

A perfect square root is where the square root of a number equals another whole number. For example, the square root of 144 is 12. 12 is a whole number thus 144 is a perfect square root.

Yes, the square root of 3 is a real number. (It is not imaginary. The square root of a negative number is imaginary.) The square root of 3 is not a rational number. It cannot be written as a fraction.

The square root is the number which is times by itself, to get the square number.

Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)

It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
