12x - 2y -4 x equals 8 and y equals -6 Is it 80 or 104?
is (2/3) -4 (that's a negative to the fourth power equal to -3/2
I don't have the correct math symbols - what I am trying to do is find out if
-3/2 is equivalent to (2/3) with a - tiny 4 - (a negative 4th power) Sorry I can't do better - I am a behavioral psych who play with primates and counts on her fingers and toes
First, please post responses as a reply in the original thread. It makes for easier reading. Hopefully one of the mods will move it there.
Apparently my guess in the other thread is correct. So as I showed there:
(2/3)^{-4} = 81/16 is NOT equal to -3/2.
Don't worry about not knowing the symbols. We'll figure it out sooner or later.
