1. The problem statement, all variables and given/known data Simplify: 1/k [(k-1) x_n+ x^k/(x_n^(k-1) )]- 1/k [(k-1)x+ x^k/x^(k-1) ] where e_n = x_n - x x_n means x subscript n e_n means e subscript n It might be easier to look at the picture I typed out in MS Word. https://www.flickr.com/photos/135306726@N08/22156107431/in/dateposted-public/ 2. Relevant equations 3. The attempt at a solution I only got [(k-1)/k]e_n + x^k/k (1/x_n^(k-1) - 1/x^(k-1)) Please help!
