I need help solving these two problems....

Question

(-9r^3/t^6) and
(30,000)(80,000)/(0.000006)(0.002)
I do not even know where to start with either of them Thanks in advance for any help provided.

Answer 1

(-9r^3/t^6)
= -9/t^3

if you meant (30,000)(80,000)/(0.000006)(0.002)

if you meant (30,000)(80,000)/((0.000006)(0.002))

then
