Homework Statement


Let ##F## be an entire function such that ##\exists## positve constants ##c## and ##d## where ##\vert f(z)\vert \leq c+d\vert z\vert^n, \forall z\in \Bbb{C}##.

Is this question incomplete? My complex analysis course is not rigorous at all and this came up on a past final exam. Can anyone help me piece this question together? Or tell me what it could possibly be asking? Thanks.

Homework Equations


Hints: Use Cauchy's Inequality and Maclaurin Series of ##f##.

I'd guess they probably want you to show that ##f(z)## is a polynomial.

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
