Question

How do you simplify `r^8/r^9` and express your answer using positive exponents?

Answer 1

`1/r` would the simplest form

Explanation:

With the rule that dividing exponents are same as subtracting their power, you can make it so that `r^8/r^9` simplifies to `r^(8-9)` which is `r^-1`. `r^-1` becomes `1/r` because you want it in positive exponents.
