As decimal expansions The square roots of the perfect squares (0, 1, 4, 9, 16, etc.) are integers. In all other cases, the square roots of positive integers are irrational numbers, and therefore their decimal representations are non-repeating decimals.

Because √2 is not an integer (2 is not a perfect square), √2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not the square of a natural number is irrational.

A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root.

The square root of a negative is undefined over the Reals because there is no Real number which, squared, is negative; it's as simple as that. There are alternate number systems (e.g. Complex numbers, Algebraic numbers) where there are numbers which, when squared, yield a negative result.

Algebraically, the absolute value of a number equals the nonnegative square root of its square. The absolute value of a number n, written |n|, can be described geometrically as the distance of n from 0 on the number line. For instance, |42| = 42 and |–42| = 42.

Is 99 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 99 is about 9.950. Thus, the square root of 99 is not an integer, and therefore 99 is not a square number.

Numbers - Square Roots - First Glance. Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers.

Yes, it will always be the positive number. The point is that, by convention, square root refers to the principal square root. You say that square root only refers to the positive, yet for the first one you say it has 2 solutions.

1 has two squares roots, 1 and -1. With the notation we pick the positive square root only. The square root of 1 is 1, by definition of the square root.

Any number times itself is a positive number (or zero), so you can't ever get to a negative number by squaring. Since square roots undo squaring, negative numbers can't have square roots.

The cube root of a number is the number which when multiplied by itself three times give you the original number. ... The square root of a number is the number which when multiplied by itself twice give you the original number. As an example, the square root of 9 is 3 because 3×3 = 9.
