In this tutorial, we define logarithm as a function which extracts the power from a number written as a power.
We then look at the standard Log Laws, and we show how to evaluate logarithm with a scientific calculator.
Finally, we use logarithm to solve power equations where the power is an arbitrary real number, which lets us easily solve compound interest equations.
