Multiply because PEMDAS

Answer: D

Reason: in PEMDAS, the P stands for parentheses- this means that that is always the first thing you should do in any equation

Example: 4(2+2)^2/8 - 3

first you do 2+2 which is 4

then you’d take that to the second power, so you’d get 16

then you’d multiply 16 by 4 to get 64

then you divide 64 by 8 to get 8

finally you’d subtract 3 from 8 to get 5
