How Do You Express a Logarithm in Terms of Common Logarithms?

Note:

If you want to find the answer to a logarithm, it can be helpful to change the logarithm so it has the common base of 10. To do that, you need to use the Change of Base Formula. This tutorial shows you how to take a logarithm and rewrite it as a common logarithm.
