like first step divide both sides by 3
OpenStudy (anonymous):
I tried dividing x^3 on both sides, but that didnt make sense
OpenStudy (anonymous):
you divide the notation by 3 too,
OpenStudy (anonymous):
thats the problem
OpenStudy (anonymous):
so now I have x^3=-8, but how do i get rid of exponent?

will be
3x^3 -24
----- = -----
3 3
OpenStudy (anonymous):
so u have x=-8
OpenStudy (anonymous):
cuz u divide ^3 by 3 too
so uhave x=-8
OpenStudy (anonymous):
careful alphadog. "so u have x=-8" is incorrect
OpenStudy (anonymous):
ooohhhh sorry

iget it
OpenStudy (anonymous):
you cannot divide the exponent by 3
OpenStudy (anonymous):
you must take both sides to the ^(1/3) power
OpenStudy (anonymous):
i didnt think so, only the 3's cancel each other out on both sides, correct?
OpenStudy (anonymous):
this makes it x^1 and = -2
