Perfect Square
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...
A number without a square root is often referred to as a "rational number" if it can be expressed as a fraction of two integers. If it cannot be simplified into such a form, it may be considered an "irrational number." Additionally, if you mean a number that is not a perfect square, it is simply referred to as a "non-square number."
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!

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 integers that are usually considered neither prime nor composite are 0 and 1 (and -1 among the negative integers). The number 1 can be described as unity or identity.
