It's hard to believe you are serious. Have you done anything on this yourself? Have you tried, for example, calculating values for, say, x= 10, 1000, etc.?
 
I studied the limit but not this type

this question is older than me :)

Just a few things that should have made this limit quite obvious -

n! < n^n, n > 2

n^2 > n

Perhaps you have seen how to evaluate the common \lim_{n\to \infty} n^{\frac{1}{n}}?

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...
