(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the roots for

[tex](z^N-a^N) = 0[/tex]

when [itex]a^N<0[/itex] is allowed.

2. Relevant equations

No idea.

3. The attempt at a solution

I know that the roots are

[tex]z_k=ae^{i(2\pi k/N)}, k = 0, 1, ... , N-1.[/tex]

How do I find that solution? I'm reading a signals book, and it assumed that this is obvious. It should also be obvious that this is not a homework problem, so if possible please just tell me what I'm missing without hints. I'm studying and in a rush. Thanks!!
