Evaluate and express as a fraction in lowest terms(adsbygoogle = window.adsbygoogle || []).push({});

-3 to the power of 4 + (-3)to the power of 3 - (-3)to the power of 2.

(I apoligize...I don't know how to type powers on the computer...>_<)

I tried to evaluate it like it told me to...so I ended up with

81-27+9

=63

Yet when I checked the answers sheet, it said the anwer was -117.

What I want to know is WHY? Am I doing something wrong? TT_____TT
