In the first tutorial I show you what a log is and how to enter logs on a calculator.

Tutorial : What is a log?

In the next tutorial I show you the basic rules needed to simplify logs with results being verified on a calculator.

Tutorial : Basic rules for simplifying logs.

Next I use the rules to do the following (You may like to try these first before looking at the worked solutions)

Logarithms are used to solve equations where the unknown is a power. In the examples that follow I demonstrate this. Again you may like to try these before looking at the tutorial and worked solutions as part of your maths revision.

This next set of equations have logs in the equation. You may want to try these first before looking at the tutorial.

In the next few examples I look at quadratic equations in exponential functions. To solve these requires the use of logs.
