Students continue an examination of logarithms in the Research and Revise stage by studying two types of logarithmsвЂ”common logarithms and natural logarithm. They take notes about the two special types of logarithms, why they are useful, and how to convert to these forms by using the change of base formula.

For example, instead of adding 3, you subtract 3. Instead of multiplying by 5, you divide by 5. When we try to find the inverse of an exponential function, we find that our algebraic means arenвЂ™t working. So, we need a new function. The logarithm is defined to be the inverse of the exponential. So, the logarithm and Questions on Logarithm and exponential with solutions, at the bottom of the page, are presented with detailed explanations.
