if the cube of a number x is equal to a, that is, the cube of x is equal to a (x^3=a), that is, the continuous multiplication of three cubic root.

any number has three and only three cube roots. they are evenly distributed on the circle with the origin as the center and the arithmetic root as the radius. the points corresponding to the three cube roots form an equilateral triangle. properties of cube roots: ⑴ any number that is not 0 has 3 cube roots. ⑵the cube root of 0 is 0. generally, if the cube of a number x is equal to a, then the number x is called the cube root (also called the cubic root) of a. that is, if x³=a, then x is called the cube root of a. 0 is the cube root of 0.
