1. The problem statement, all variables and given/known data I am wondering how you are meant to solve something like log_10(x)^2 = 0. What does multiplying and dividing do to the log function algebraically, I can easily tyoe into a calculator, but I don't know how to work it out on paper. My text book does not cover how to do these types of questions, but it does have those types of questions. 2. Relevant equations The other log rules, maybe? 3. The attempt at a solution It can be re-written as log_10(x)*log_10(x), but it really doesn't get me very far. I have tried a whole bunch of different methods, including rearranging some of the log rules, but to no avail.
