In mathematics, a square root of a number X is a number R such that

R^{2} = X

, or in words, a number R whosesquare (the result of multiplying the number by itself) is X. Every non-negative real number has a unique non-negative square root, called the principal square root and denoted with a radical symbol as

\sqrt{X}

.
Every positive number X has two square roots. Oneof them is

\sqrt{X}

, which is positive, and the other

- \sqrt{X}

, which is negative. Together, these two roots are denoted

\pm \sqrt{X}

.
So the square root of

64 = \pm \sqrt{64}

= \pm \sqrt{8 * 8}

= \pm 8

Answer: the square root of

64 = \pm 8
