Question

This problem is pretty easy but for some reason I seem to not be able to get the correct answer.
Question: What is the numerical value of x^3z-3xy
when x=2, y=4, and z=8?
A. 32
B. 40
C. 88
D. 104

Answer 1

plug in 2 for x, 4 for y, and 8 for z
so ((2)^3 *(8)) - (3*(2)*(4)) and use order of operations (PEMDAS)

Answer 2

the answer is 40 correct

Answer 3

yes :)
