Simplify:
3x (to the 2 power)
2x(3rd power)times x(to the 2 power) times x(to the 7 power)
3x (to the negative 3 power) times (4 power)

I searched Google under the key words "math power" and "math power negative" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
