help me but dont give me the answer plz

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

8-4/3(-4/3 is a fraction)

OpenStudy (anonymous):

well make 8 into a fraction with the same denominator(3)

OpenStudy (anonymous):

24/3?

OpenStudy (anonymous):

yupp! so then just do 24/3-4/3 which gives you?

OpenStudy (anonymous):

combind them?

OpenStudy (anonymous):

no subtract them..

OpenStudy (anonymous):

20/3?

OpenStudy (anonymous):

|dw:1366253185297:dw|

OpenStudy (anonymous):

yupp! :D

OpenStudy (anonymous):

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)

OpenStudy (anonymous):

yeah.

OpenStudy (anonymous):

@jim_thompson5910 do you have any ideas?

OpenStudy (anonymous):

(-4/3)

OpenStudy (anonymous):

8-(-4/3)?

jimthompson5910 (jim_thompson5910):

so is it 8 times (4/3) ? no that wouldn't work either

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))

OpenStudy (anonymous):

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 :(

jimthompson5910 (jim_thompson5910):

don't be, you probably made a silly mistake

OpenStudy (anonymous):

yeah taking an exam while hardly awake was a silly mistake!
