Answer:
Step-by-step explanation:
Your equation is: 
You also know that x = -3 and y = 2. You can rewrite the equation by substituting x and y with their actual values:
First, you want to do the exponentiation (meaning you want to calculate
and
parts).
equals 9 and
equals 16.
So the equation now is:

Now you want to do multiplication.
equals 36 and
equals 32. So you're left with:

Which equals 68.
