Homework Help: Algebra 2

Posted by Ann on Sunday, September 11, 2011 at 2:00am.

Exponential Notation

Simplify.
(-2)^0-(-2)^3-(-2)^-1+(-2)^4-(-2)^-2

I tried solving this problem a few times and kept getting random answers. The answer in the book says that it is 25 1/4
I do not understand how you get that answer.

Thanks For Your Help
