If the absolute value of the square of (a + 2) + B-3 is equal to 0, what is the cubic power of a + B

If the absolute value of the square of (a + 2) + B-3 is equal to 0, what is the cubic power of a + B

The absolute value of the square of (a + 2) + B-3 is equal to 0
Then, a + 2 = 0, B-3 = 0
a=-2 b=3
The third power of a + the third power of B
=(-2)^3+3^3
=-8+27
=19
