# Math Help - complex analysis

1. ## complex analysis

Help me please to prove this one:

Let us $f(z)\; and \; z^{5}\ \overline{f}(z)$ both are entire functions.
Prove that $f(z)$ is constant function necessarily.

Thanks

2. The only way I can see this happening is to show that f is bounded, the result then follows from Liouville's theorem
