(Hint:write w in terms of polar coordinates.)  \begin{proof}  Let $n \in \mathbb{Z}$ and $w \in \mathbb{C}.$ So, in polar coordinates, $w=re^{i\theta}$ for some $r,\theta \in \mathbb{R}.$ Notice that the $r$ represents the modulus of the complex number and $\theta$ is the argument. So, we have $z^n=re^{i\theta}.$\\  Geometrically, we are multiplying the lengths and add their angles. //  We need to find values of $z$ where it is multiplied by itself $n$ times and is equal to $re^{i\theta}.$  \end{proof}  \end{problem}
