Answer:
Explanation:
There's more than 1 way this can be represented.
a: a^-8/a^-5
a: a^(-8 + 5)
a: a^-3
=======
b: b / b^3
b: b^(1 - 3)
b: b^(-2)
=======
So one of the answers could be
a^-3*b^-2
Another could be
1/(a^3*b^2)
There are other ways, but these are the main 2. If you have choices list them.
