Solving a Logarithmic Equation - Problem 6


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.
