did you know that (-2)^4=16 ? or did you think it was negative?
anonymous
  • anonymous
i know it equals 16 but the negative sign infront of the x threw me off.

what would it be if it was a -1 instead of a -2?
TuringTest
  • TuringTest
\[(-1)^4=(-1)(-1)(-1)(-1)=(1)(1)=1\]

  • anonymous
ok i got that wrong too. i wrote -3
anonymous

wait, so \[-1^{4}-4\]=1?
TuringTest
  • TuringTest
no, I just did the (-1)^4 part, try the rest yourself!

-5
