Question

Jacki evaluated the expression below

2^3(3-1)+4(8-12)
2^3(2)+4(4)
8(2)+16

What was Jacki’s error?

B.Jacki should have multiplied 4 and 8 first.
C.Jacki should have multiplied 4 and 8 first.
D.Jacki should have multiplied 4 and 8 first.

Answer 1

none of the answer above is right,
Jackie made an error where 8-12=-4 instead he wrote 4
so the actual answer is 0 as,
2^3(3-1)+4(8-12)
2^3(2)+4(-4)
8(2)-16
16-16
0
