Answer:
Explanation:
First, break the question down into individual parts:
For
:
Use the exponent law that states
For this problem, let a=4 and m=-2
So,
For
:
Use the exponent rule that states
For this problem, let a=8
So,
Since the prompt states the solution must have positive exponents and
already has positive exponents, it can be assumed
does not need to be manipulated.
Next, insert the derived values above into the original problem:
