Hard to tell until you post the question :wink:
 
yes, telling us where to find y prime FROM would be helpful :D
 
I find nothing wrong with your solution. :smile:
 
Or anything right, for that matter.
 
Your question stumps me. my guess to the solution would be dirty rabbit eating, fox wearing donkey butt. I am pretty confident this is right. Ask your professor, he will
probably say the same.
 
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...
