A thorough treatment of the laws of logarithms, how they relate to the laws of exponents, and examples of each.

The University of Saskatchewan offers a brief but quality description of logarithms with a list of rules and a number of exercises of varying difficulty.

Three properties of logarithms are presented here (product, quotient, and power properties). Examples are provided to demonstrate how to use the properties to expand and simplify logarithmic expressions.

This tutorial contains 13 lessons on logarithms and exponential functions including exponential shortcuts and rules, graphs and rules of logarithms, and many more.
