Homework Help Forum: 7th grade Pre-Algebra

Posted by Dean on Tuesday, September 22, 2009 at 9:02pm.

Using the definition, 10(to the negative sixth power) = 1/10to the six power and x(negative2) = 1/xto the second power The definition also shows that 1/10to the six power = 10to the negative 6th power and 1/xto the 2nd power = x(negative2) I think thats the directions :S 1. 3to the negative1st power :? Sorry, I'll retype the directions if you get confused, I, aswell, am confused. :/ Please help, Appriciated.
