You call them principal square roots.
A square root is the number that is squared to obtain a square number so it can therefore be considered a root of that square number (or basis for that square number). It can also be noted that each square number, when displayed using dots will always form a perfect square perhaps giving it it's name e.g. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . etc...
Finding the square root. Remember, though that there are two square roots for every positive number the square roots of 9 are 3 and -3 because 3 * 3 = 9 and -3 * -3 = +9
The product is a perfect square.
Are you talking about negative powers.

Any positive number x has two square roots: one positive and one negative. For example, +3 and -3 are both square roots of 9. Using a brilliant leap of imagination, mathematicians decided to call the first of these the positive root!
