Answered here!
My teacher assigned me this assignment and it looks totally different that what we did... here are a few of the problems...
X^-2 Y^4
C^0 D^4
R^-3 T^5
There is just a couple of them I just want to get the hang of it so I can do the rest.
To review lots of worked exaples and learn how to work with negative exponents, try some online lessons.
As many of the lessons in the above link will mention, anything to the zero power is just "1".
