You just have to plug in numbers for this.

Answer 8

\[c_1 = (-1)^1 + 1 = ?\]

Answer 9

Do the same with 2 and 3.

Answer 10

@iambatman still stuck, none of the numbers work when I plug them in

Answer 11

@perl can you help me with this?

Answer 12

What do you mean, what is \[(-1)^1+1\] ?

Answer 13

Anything to the power of 1 just means it's the number alone, so for example:

\[2^1 = 2, ~~~4^1 = 4\]
and if you have something such as \[2^2 = (2)(2)\] note that it's being multiplied.

Oh ok. I got C, is that right? @iambatman
