Refresher

 

Use the “Exponent” applet to review the definition of exponent. Follow the links from there to explore the definitions of power and base. Click on “power” to use the demonstration applet to apply the definitions.



Try “Exploring Laws of Exponents” to review the exponent laws. There are seven laws altogether. The first six were covered in your previous math studies. The seventh one, the negative exponent law, will be introduced in this lesson.

You will want to select the “Explore It” tab at first. You can either explore the applet on your own or if you prefer to have some structure to your exploration, choose the “Print Activities” option to use with the applet.
