# Radius & interval of convergence of power series

## Homework Statement

i was doing this exercise and came across this example.

Ʃ (x^n)/ln(n+1)
n=1

## The Attempt at a Solution

i know you have to do the ratio test which is
lim | a(n+1)/a(n)|
n>∞

i got to

lim | [x ln(n+1)] /ln(n+2) |
n>∞

and have no idea how to continue? is there a way to get rid of the logs? since in this case as n>∞ the top and bottom just goes to ∞?
