Quick Reference

• 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.
• Negative and fractional powers
  This leaflet explains the use of negative powers and fractional powers.
• Negative and fractional powers
  This leaflet reminds students how to interpret negative or fractional powers.
• Powers and roots
  This leaflet reminds students about the meaning of powers, square and cube roots.
• The laws of indices
  This leaflet reminds students of the laws used for manipulating indices.

Video

A transcript of each video should be available in the Teach Yourself section above.

These videos require Windows Media Player (v10).

Please note: You may experience trouble with more recent upgrades to Internet Explorer (now v.7) and Media Player (now v.11). These no longer support streaming from the mms servers used by mathcentre, so we are recommending that you uninstall IE7 (IE6 lies underneath) and replace the new version of WMP with the fully functioning v.10 (you may need to find a download via google after uninstalling v.11). All those that have done this have reported back that everything is working again.

• Powers
  A knowledge of powers, or indices as they are often called, is essential for an understanding of most algebraic processes. In this section you will learn about powers and rules for manipulating them through a number of worked examples. (Mathtutor Video Tutorial)
