Answer:
1
Step-by-step explanation:
Raise -2 to the power of 3 = -8
9-8= 1
A number raised to the 3rd power is equal to that number multiplied by itself twice. Below I have expanded the expression to visualize this process. If this makes it more confusing, the main way is just to go from line 1 to line 4.
9 + (-2)³ <---- Original expression
9 + (-2 x -2 x -2) <---- (-2)³ expanded
9 + (4 x -2) <---- -2 times -2
9 + (-8) <---- 4 x -2
1 <---- 9 - 8
180 - 36? I dont exactly remember how to do this
