1. The problem statement, all variables and given/known data Express in terms of logarithms x, y, z or w. Problem: loga(x8w/y2z4) 2. Relevant equations log(u/w) = log u - log w log(uw) = log u + log w 3. The attempt at a solution Here are my attempts: As you can see, the answers are pretty similar. I'm assuming I made a small syntactical mistake.
