Homework Statement
Find the roots for
[tex](z^N-a^N) = 0[/tex]
when [itex]a^N<0[/itex] is allowed.
Homework Equations
No idea.
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!
