This lesson on logarithms starts from the idea of logarithms, where they come from, and how they are related to exponential functions that was explained in the first lesson. It begins with a quick recap and then goes into a more intensive examination of simplifying logarithmic expressions and solving logarithmic equations. This is a great tutorial for learning how to evaluate logarithms.
