set u=2x+1 and do u-substitution
 


ok! I get it. I was looking in the wrong part of the book and I thought the directions said to use part 2 of the fundamental theorem! So I was freaking out because I was sure the theorem couldn't be used for this. thanks! sorry I asked a stupid question.
 


haha no problem. there are no stupid questions! :smile:
 

Thread 'Finding the nth roots of a complex number'

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...
