One of the \(5^{\text{th}}\) roots of \(\omega\) is
Show Hint
The \(n^{\text{th}}\) roots of
\[
\operatorname{cis}\theta
\]
are
\[
\boxed{
\operatorname{cis}\left(\frac{\theta+2k\pi}{n}\right),
\qquad
k=0,1,\ldots,n-1.
}
\]
Always use this formula to find the roots of a complex number in polar form.
