OpenStudy (moongazer):
let x=4
-x^4 = -256
is this correct?

not
-x^4 = 256
because this -x^4 means
-1(4)^4 not (-4)^4
OpenStudy (moongazer):
Is it correct?
OpenStudy (anonymous):
nop
OpenStudy (anonymous):
it is 256
OpenStudy (theviper):
(-x)^4=256 & -(x^4)=-256

becoz instead of x u r giving 4
OpenStudy (theviper):
Does that help @moongazer ??
OpenStudy (anonymous):
-4 * -4 * -4 * -4=
OpenStudy (theviper):
Becoz according to BODMAS rule first we solve brackets :)
OpenStudy (moongazer):
so
-x^4 = -256
is correct right?

OpenStudy (anonymous):
but it is like this (-4)^4
OpenStudy (moongazer):
But there is no parenthesis ?
OpenStudy (moongazer):
so it is like -1(x)^4
OpenStudy (anonymous):
or wat is -x*-x*-x*-x
OpenStudy (anonymous):
nw give x=4

wat will the answer
OpenStudy (anonymous):
just think like that
OpenStudy (anonymous):
-x^4=-x*-x*-x*-x
OpenStudy (moongazer):
isn't that
\[-4^2 \neq (-4)^2\]

???
OpenStudy (anonymous):
why both r same
OpenStudy (moongazer):
no it is not
OpenStudy (anonymous):
why>>>>>>

ok.....@moongazer nw tell is this correct or not
-x^4=-x*-x*-x*-x
OpenStudy (anonymous):
@moongazer
OpenStudy (moongazer):
That is wrong I think.
OpenStudy (lgbasallote):
-x^4 = -256
for the record...

indeed
OpenStudy (moongazer):
that's the question I am asking :)
OpenStudy (lgbasallote):
so i guess it's down to a 2-on-2
OpenStudy (anonymous):
why //
OpenStudy (anonymous):
@lgbasallote -x^4=-x*-x*-x*-x

@Yahoo! this is -(x^4) not (-x)^4
OpenStudy (lgbasallote):
because the exponent just affects the nearest base
OpenStudy (anonymous):
look his question it is just -x^4
OpenStudy (lgbasallote):
exactly
OpenStudy (lgbasallote):
the ^4 is just on x...not on - too

OpenStudy (moongazer):
because -x^4 is like -1(x)^4
not (-x)^4
I think this is the explanation?
OpenStudy (anonymous):
i would say if (-x)^4=256 & -(x^4)=-256
OpenStudy (lgbasallote):
-x^4 = -(x^4)
OpenStudy (anonymous):
so wat is -2^2
OpenStudy (lgbasallote):
-4

OpenStudy (moongazer):
@Yahoo! (-1)(4)
so -4
OpenStudy (anonymous):
-2^2 = -1 (2^2) = -1 * 4 = -4
OpenStudy (anonymous):
when there is a minus, do all the stuff before minusing
OpenStudy (anonymous):
hey ..... it is like this (-x)^4=256 & -(x^4)=-256

(-x)^4=256 -x^4 = -256 ................ agreed
