Sal gets to the heart of the matter in this video, clarifying that it's important to understand math "so you can actually apply it in life later on and not have relearn everything every time." True to his word, Sal demonstrates ways to more easily and intuitively solve logs and exponents with several well-explained examples.
By using the definition of a logarithm and the rules of exponents, Sal proves the Product Property of Logarithms in this video. He does a nice job of helping the listener develop an intuitive understanding of what a logarithm is.
In this thought-provoking video, Sal shows how a typical linear scale is different than a logarithmic scale. He plots numbers on both scales and compares them to show why the logarithmic scale is useful. This video gives a nice intuitive explanation that is easy to follow.
This video shows how to convert an equation in exponential form to logarithmic form. The example shown uses base e, and it is converted to an equation using a natural logarithm.
