Answer:
The answer is 729/64.
Explanation:
I would first simplify the equation.
In the denominator, you can get rid of b^0 because that just equals 1.
For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.
Equation:
Now, you can subtract a and a^3. This would be 1/a^2.
Equation:
Now, you can square the whole equation.
Equation:
This is the simplified equation. Now you can plug in -2 and -3.
