A) -1
B) -2
C) 2
D) 0
E) 1

Are some of those values supposed to be exponents?
If so, please use "^" to indicate this.
For example, write n2 as n^2

I have a feeling that one of more of the other terms involve exponents as well, so we need you to edit the question before it can be answered.

Hi sgr21,

Brent makes a good point about using proper notation in your questions.

This is a symbolism question and a fairly straight-forward one. To solve it, you'll have to follow the "instructions" in the prompt. Plug in n = 2 and z = 2 and then do the calculation. You'll have the correct answer.
