check work and answer?

OpenStudy (studygurl14):

@hartnn @iGreen

OpenStudy (studygurl14):

\(\Large\sqrt[3]{2x^2}\sqrt{2x}\)

hartnn (hartnn):

correct again! you're on fire :D

OpenStudy (studygurl14):

wait...that's not one of my answer choices...

hartnn (hartnn):

they might have combined it

OpenStudy (studygurl14):

How would I do that?

hartnn (hartnn):

what is the lcm of 1/3 and 1/2 ?

OpenStudy (studygurl14):

1/6 ?

OpenStudy (studygurl14):

oh..i think i know where you're going...

hartnn (hartnn):

and does any of the answer choices have something like \(\sqrt[6]..\)

OpenStudy (studygurl14):

yeah

hartnn (hartnn):

then you know how to proceed? :)

OpenStudy (studygurl14):

yeah \(\Large (2x^2)^{\frac{2}{6}}(2x)^{\frac{3}{6}}\rightarrow\sqrt[6]{2x^2x^4}\sqrt[6]{2^3x^3}\) does this look like the right track?

OpenStudy (studygurl14):

sorry, ignore the x^2

hartnn (hartnn):

2^2 = 4 in the first bracket

OpenStudy (studygurl14):

yeah, typo

OpenStudy (studygurl14):

Thanks @hartnn I think I got it. :)

hartnn (hartnn):

yes, other things look fine...ohh welcome ^_^
