|dw:1316390157547:dw|

OpenStudy (anonymous):

i got 2t^2(sqrt3)

OpenStudy (mrsmarsh):

not quite

jimthompson5910 (jim_thompson5910):

should be \[\Large 2t^2\sqrt[3]{3t^2}\]

OpenStudy (anonymous):

you can pull out a t^2 and split the 24 up into 8x 3

OpenStudy (saifoo.khan):

that will be a cube root @ pixie.

OpenStudy (anonymous):

that is where jim got his answer

OpenStudy (anonymous):

how did you end up with a t^2 under the sqrt?

OpenStudy (anonymous):

because t^8 = (t^2)^4

OpenStudy (anonymous):

you are left a t^2

OpenStudy (anonymous):

but isn't t^8 a cube? and the cube would be t^2?

OpenStudy (anonymous):

\[\sqrt[3]{t^2*t^2*t^2*t^2} = t^2\sqrt[3]{t^2}\]

OpenStudy (anonymous):

when you * polonomials you add them unlike constants

OpenStudy (anonymous):

no jim is correct

OpenStudy (anonymous):

add the degrees i mean >_<

OpenStudy (anonymous):

ok, when you write it like that, it makes sense lol, i just really hate math and don't really understand it most of the time lol, thanks for ya'lls help!

OpenStudy (anonymous):

were you ever taught this way in doing roots and stuff? this is how most teachers teach it

OpenStudy (anonymous):

yeah, but algebra just doesn't click unless i can see it done, i am in college and my materials don't show alot of examples, which is how i learn this kind of stuff
