Homework Statement


I'm studying for my final exam and came across this problem:
Let f and g be entire analytic functions and |f(z)|<|g(z)| when |z|>1. Show that f/g is a rational function.


The Attempt at a Solution


I really have no clue where to go :(

Well, you know that since |f(z)|<|g(z)| on |z|>1, f(z)/g(z) is bounded on |z|>1. Does this tell you anything?
 
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...
