Hint:
$a^2+b^2=0 \Leftrightarrow a=0,b=0$
Please read Forum Guide and Rules before you post.

Use $L^AT_EX$, It makes our work a lot easier!

a request to the authority - i think this topic should be moved to any other problem forum.as it has nothing to do with the camp or inequality.
\[\sum_{k=0}^{n-1}e^{\frac{2 \pi i k}{n}}=0\]
Using $L^AT_EX$ and following the rules of the forum are very easy but really important, too.Please co-operate.
