Resource type Indices or Powers
A power, or index, is used when we want to multiply a number by itself several times. This leaflet explains the use of indices and states rules which must be used when you want to rewrite expressions involving powers in alternative forms.
Resource type Negative and fractional powers
This leaflet explains the use of negative powers and fractional powers.
Resource type Negative and fractional powers
Sometimes it is useful to use negative and fractional powers. These are explained in this leaflet.
Resource type Powers and roots
This leaflet reminds students about the meaning of powers, square and cube roots.
Resource type Powers and roots
Powers are used when we want to multiply a number by itself repeatedly.
Resource type The exponential constant e
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.
Resource type The laws of indices
This leaflet reminds students of the laws used for manipulating indices.
Resource type The laws of indices
When a number is to be multiplied by itself, a power or index can be used to write this compactly. In this leaflet, we remind you of how this is done, and state a number of rules, or laws, which can be used to simplify expressions involving indices.
