If you can isolate a log and get an equation into the form log x = constant, then you can solve by writing it in exponential form. Remember to check your solution by plugging it back in we must be wary of extraneous solutions. Multiple methods are usually possible, so don't be afraid to switch to a different method if you're getting stuck.
