http://www.freemathvideos.com In this video series you will learn the basics of logarithmic and exponential functions. We will start off by converting between exponential and logarithmic expressions. We do this so that we can understand what a logarithm represents. Once we have what a logarithm represents we are able to evaluate logarithms without a calculator. This next process that will be helpful for us is expanding and condensing logarithmic expressions. We will do this using the rules of logarithms. This will help us prepare for solving logarithmic equations which we will do next in addition to solving exponential equations.
