The answer is -720.
An exponent simply means multiplying a number by that same number.
So, plugging -2 in for x, you have -2*-2*-2, which equals -8.
Then, plugging -3 in for y, you have -3*-3, which equals 9.
Since the numbers are sitting right next to each other, it's multiplication.
-8*9= -72
Remember, there is also a 10 sitting out front. So multiply the -72 by 10 and your final answer ends up being -720.
