okay thats not correct... None of the answer say that :/
OpenStudy (anonymous):
did you copy it down right?
jimthompson5910 (jim_thompson5910):
you may have to convert to a mixed number
OpenStudy (anonymous):
16
-16
-1/16
1/16
OpenStudy (anonymous):
did you copy it down right? 8-(4/3)

yeah.
OpenStudy (anonymous):
@jim_thompson5910 do you have any ideas?
OpenStudy (anonymous):

No the fractions a negative
OpenStudy (anonymous):
8 divided by -4/3 maybe
jimthompson5910 (jim_thompson5910):
ooooh, 8 to the 4/3 power
OpenStudy (anonymous):
OHH!
jimthompson5910 (jim_thompson5910):
-4/3 power i mean
8^(-4/3) = 1/(8^(4/3))

idk this pellet fluttering sucks like i said @jim_thompson5910
jimthompson5910 (jim_thompson5910):
8^(-4/3) = 1/(8^(4/3))
8^(-4/3) = 1/((cube root of 8)^4)
8^(-4/3) = ???
OpenStudy (anonymous):
i completely lost
jimthompson5910 (jim_thompson5910):
\[\Large 8^{-4/3} = \frac{1}{8^{4/3}}\]
\[\Large 8^{-4/3} = \frac{1}{\left(\sqrt[3]{8}\right)^4}\]
\[\Large 8^{-4/3} = ??\]
OpenStudy (anonymous):
i don't know. like never learned this. ummm \[(2\sqrt[3]{4})^{4} \] I feel i did that wrong

jimthompson5910 (jim_thompson5910):
the cube root of 8 = ???
OpenStudy (anonymous):
I give up. forget it. one wrong answer wont kill me. this is giving me a big headache and im flipping beyond sleepy.. thanks tho. :)
jimthompson5910 (jim_thompson5910):
ok I'll finish it up
\[\Large 8^{-4/3} = \frac{1}{8^{4/3}}\]
\[\Large 8^{-4/3} = \frac{1}{\left(\sqrt[3]{8}\right)^4}\]
\[\Large 8^{-4/3} = \frac{1}{2^4}\]
\[\Large 8^{-4/3} = \frac{1}{16}\]
jimthompson5910 (jim_thompson5910):
The cube root of 8 is 2 since 2^3 =8
OpenStudy (anonymous):
are you for real. I feel stupid :(
