Resource type Logarithms 1
Logarithms appear in all sorts of calculations in engineering and science, business and economics. Before the days of calculators they were used to assist in the process of multiplication by replacing the operation of multiplication by addition. Similarly, they enabled the operation of division to be replaced by subtraction. They remain important in other ways, one of which is that they provide the underlying theory of the logarithm function. This has applications in many fields, for example, the decibel scale in acoustics.

Resource type Indicial equations
An indicial equation is one in which the power is unknown. Such equations often occur in the calculation of compound interest.
Resource type Logarithms
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
Resource type Logarithms - changing the base
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.
