Square Root The square root of a nonnegative number is a number that, when multiplied by itself, is equal to that nonnegative number. Square roots have positive and negative solutions. The symbol represents a square root. Taking the square root of a number is the opposite, or inverse, of squaring the number.

Solving Square Roots

Cube Root To find the cube root of a number, find the number that, when multiplied by itself two times (a total of three factors), is equal to that number. The symbol represents a cube root. Taking the cube root of a number is the opposite, or inverse, of cubing a number (raising a number to the third power).
