Question

Jacki evaluated the expression below.

2 cubed (3 minus 1) + 4 (8 minus 12) = 2 cubed (2) + 4 (4) = 8 (2) + 16 = 16 + 16 = 32.

What was Jacki’s error?

Answer 1

C Jack did not subtract 12 from 8 correctly

Explanation:

`2^3(3-1)+4(8-12)=2^3(2)+4(-4)`

it should be -4, not +4

Answer 2

Jackie didn’t subtract 12 from 8 right, I think
