Rational Exponents & Other Roots

Rational exponents, like an exponent of 2/3, can be extremely confusion.  How do you raise a number to the 2/3rds power anyway?  If you’re only learning what to do, how to manipulate them, without understanding what the notation really means, this confusion is almost insurmountable.  

This page is designed to help you understand what rational exponents, and other roots (indices) mean, and how they’re related.  This will help you to have an easier time dealing with math that uses this notation, but also remember and better understand the math.  

The tabs below organize the resources at your disposal.  Read through, and take notes from, the information in the first tab.  You can use the lesson tab to download a PowerPoint less, which can help provide further clarity.  Try the assignment to test your understanding, then watch the video to help you gain greater insight and to help you compress what you understand.

If you’re a teacher and would like to have an organized, easy to use and reference zip file of all of the materials found on this page, and materials not published on this site, consider downloading the Exponents Packet.
