Evaluating a Logarithmic Expression in terms of Known Quantities :
In order to do problems on evaluating logarithms in terms of known quantities, we need to understand the rules of logarithms such as the product, the quotient and the power rules. When we say evaluating logarithms in terms of known quantities, we mean that we want to be able to rewrite a complex logarithm so that we can recognize certain simpler logarithmic terms within it.

 

 

Solving a Logarithmic Equation with Multiple Logs :
When given a problem on solving a logarithmic equation with multiple logs, students should understand how tocondense logarithms. By condensing the logarithms, we can create an equation with only one log, and can use methods of exponentiation for solving a logarithmic equation with multiple logs. This requires knowledge of the product, quotient and power rules of logarithms.
