 However, it is always the case that

A modest extension of the version of de Moivre's formula given in this article can be used to find the th roots of a complex number (equivalently, the power of ).If is a complex number, written in polar form as

then the th roots of are given by

where varies over the integer values from 0 to .This formula is also sometimes known as de Moivre's formula.
