When your goal is to solve for x and x is in an exponent, you'll need to either rewrite the equation in log form or else apply a log to both sides. Both methods are explored here, in particular when the base is e. It is important to understand both methods, if nothing else, because you'll want to have an alternative method if you get stuck. Also, don't underestimate the need to practice both exact solutions and decimal approximations.
