Dr. Eaton begins Common Logarithms with real world applications, how they are written, and how they utilize base 10. Next are how to deal with equations and inequalities that have common logs as well as the change of base formula. Four examples at the end make sure you have plenty of practice.
Solve exponential equations by taking the common log of both sides of the equation. You can then use a calculator to get a decimal approximation of the answer.
If you want to get a decimal approximation of a logarithmic expression, convert the log expression to a log expression to the base 10 using the change of base formula. Then use a calculator to evaluate the new expression.
