Question

Simplify the expression

Answer 1

`\cfrac{r^(-3)s^5t^2}{r^2st^(-2)}`


`= r^(-3-2)s^(5-1)t^(2+2)`


`= r^(-5)s^4t^4`


`= \cfrac{s^4t^4}{r^5}`

Answer 2

For this case, what we should do is follow the following steps:
1) rewrite the expression using power properties
2) cancel similar terms
3) add exponents that have the same base.
