Negative and fractional powers 
Worksheet 
A power, or an index, is used when we want to multiply a number by itself several times. It
enables us to write a product of numbers very compactly. The plural of index is indices. 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.
