This seems pretty easy, but I cannot seem to have a possible solution for it and it goes: **PROBLEM**: If $a>e$, show that the equation $e^z = az^n$ has $n$ solutions inside the unit circle. Can someone show me how to do these roots problems formally so I can follow up and continue other problems? I would appreciate the help. ( Im studying for my finals atm so I dont have much time to spend each time thinking about problems I am stuck at so I ask for help here).

This is a straight forward application of Rouche's theorem.
