Question

How do you simplify `(9s^-5r^-6)/(3sr^-2)`?

Answer 1

Rewrite the whole thing so there are no more negative exponents remaining, then combine/cancel like-terms.

Explanation:

`=[(9/s^5)*(1/r^6)]/(3s*1/r^2)`

`=(9/(s^5r^6))/((3s)/r^2)`

`=(3cancel9cancel(r^2))/(1cancel3s^6cancel(r^6)r^4)`

`=3/(s^6r^4)`
