Soo 4*-4?
OpenStudy (anonymous):
-4*4=-16
OpenStudy (mrnood):
is this meant to be
\[-4^{4}\]
OpenStudy (anonymous):
Yeah
OpenStudy (anonymous):
For future reference, just use this key to show a square: ^. So it would be shown as (-4)^4

(-4)^4
OpenStudy (mrnood):
well raise to an even power means that the negative goes away
(e.g. -2 * -2 = -2^2 = 4
so this is the same as 4^4
OpenStudy (anonymous):
it =
-16 right
OpenStudy (anonymous):
?
OpenStudy (anonymous):
(-4)^4=-256

@DrumRBoy1927
look at it as
-4 * -4 *-4 *-4
you know that multiplyint TWO negatives gives a positive
so does multiplying FOUR negativex

@cb77613
It is against the code of conduct to post direct answers - and it does not help the original poster either
OpenStudy (anonymous):
You guys are confusing me
OpenStudy (mrnood):
@DrumRBoy1927
have another look at it as
(-4*-4) * (-4*-4)
you can see it ends up as a positive
