An indicial equation is one in which the power is unknown. Such equations often occur in the calculation of compound interest.

We use logarithms to write expressions involving powers in a different form. If you can work confidently with powers, you should have no problems handling logarithms

Sometimes it is necessary to find logs to bases other then 10 and e.
There is a formula which enables us to do this. This leaflet states
and illustrates the use of this formula.

Logs can be used to solve equations when the unknown occurs as a power. This leaflet explains how.

The letter e is used in many mathematical calculations to stand for a particular number known as the exponential constant. This leaflet provides information about this important constant, and the related exponential function.

There are rules, or laws, which are used to rewrite expressions involving logs in different forms. This leaflet states and illustrates these rules.

There are a number of rules known as the laws of logarithms. These allow expressions involving logarithms to be rewritten in a variety of different ways. The laws apply to logarithms of any base, but the same base must be used throughout a calculation.
