Question 10074: Ok...here is a problem that I think I did right, but not sure. Can someone check it for me?
Simplify: (6^3)(6^-5) (x^7)(x^-3)
This is what I did. Not sure if it is right though.
6^3 * 6^-5 = 36^-2
x^7 * x^-3 = x^-21
so my answer was (36^-2)(x^-21)
If this is wrong, can someone show me how they got the answer?
Thanks
