Question

Explain how you solved this problem.

Answer 1

Start with PEMDAS.
Do (4+-2) (4+-2) (4+-2)
Then multiply your answer by 2, so you’ll have -2(8), which gives you -16,
Lastly you would have -4-16
And then your final answer would be -20

Answer 2

(-20)

Explanation:

-4 - 2(4 + (-2) )³ = -4 - 2(4 - 2)³

= -4 - 2*(2)³

= -4 - 2* 8

= -4 - 16

= -20
