OpenStudy (solomonzelman):

Anytime, just tell me what you got to make sure you have it right....

OpenStudy (anonymous):

1/32

OpenStudy (solomonzelman):

not exactly, it's \[1/-32\]

OpenStudy (solomonzelman):

because you are taking -2 to the 5 and 5 is an odd number.

OpenStudy (anonymous):

oh right, I didn't think of that, thank you :)

OpenStudy (solomonzelman):

Anytime, the main thing is that you get it, and I am sure you do.
