Homework Statement


The sequence is a_n = \frac{n^P}{e^n}


Homework Equations





The Attempt at a Solution


If I did L'Hopital's rule P times, would the final product look like:

P!\times lim_{n \rightarrow \infty} = \frac{1}{e^n} ?

I don't see why it wouldn't
 
I just wasn't sure if I had wrote it properly. Thank you.
 
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...
