Hey! Could anyone post solvation of lim x->+eternety (x - x^2*ln(1 + 1/x)) using Taylors formula? Need to go to exam in 1 hour, would be so thankful for person who could answer thatin this time :D (desperate)

P.s.: not full solvation ofc, just main steps
 
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...
