1. The problem statement, all variables and given/known data http://img132.imageshack.us/img132/6663/captureqqi.jpg [Broken] 2. Relevant equations 3. The attempt at a solution I came up with this answer and i dont know how to continue: (1+1/n)^n I understand I have to put in limit n -> infinty. But can i put the limit inside the bracket? So i will get an answer of 1 ? So ultimately, the ratio test is inconclusive?
