HI!!

misty1212 · Answer

you have a couple of choices
one is to first multiply each exponent inside the parentheses by $-4$ 
maybe that is the easiest

misty1212 · Answer

you should get $$\huge \frac{r^{20}s^{12}}{r^{-32}s^8}$$

misty1212 · Answer

does that look right? 
( you are not done yet)

anonymous · Answer

Yes that's what I got!! Thank you! @misty1212

misty1212 · Answer

got logged out, sorry
still not done though right?

misty1212 · Answer

the $r^{-32}$ comes up to the numerator as $r^{32}$

misty1212 · Answer

and $$\frac{s^{12}}{s^8}=s^{12-8}=s^4$$

misty1212 · Answer

so you end up with $$r^{20}r^{32}s^4$$ then add the exponents  for the $r$ terms

Perfect! I just needed to simplify the first part but I got it! @misty1212
