1. The problem statement, all variables and given/known data Given an infinite series that follows the form [(xlna)^(n-1)]/n! n takes on integers from 0 onwards x all real numbers a all positive real numbers 2. Relevant equations Maclaurin series expansion 3. The attempt at a solution In which for the e^x series expansion plug in xlna into the x from e^x to obtain a^x which is the answer to the infinite summation. However, are there any other proofs besides using Maclaurin? Thanks.
