Cube root

Number whose cube is a given number

In mathematics, a cube root of a number x is a number y that has the given number as its third power; that is y 3 = x . {\displaystyle y^{3}=x.} The number of cube roots of a number depends on the number system that is considered. Every real number x has exactly one real cube root that is denoted x 3 {\textstyle {\sqrt[{3}]{x}}} and called the real cube root of x or simply the cube root of x in contexts where complex numbers are not considered.
