I need help solving this problem. Can someone show me how?

OpenStudy (anonymous):

\[\frac{ 4\sqrt{6} }{ \sqrt{30} }\]

OpenStudy (anonymous):

I need to simplify that.

OpenStudy (anonymous):

@Nnesha Do you know how to work these?

OpenStudy (anonymous):

times root 30 at top and bot, then you get 4*root180 over 30, after factor out the 180 and divided by 30, you get 4*root 5 over 5

OpenStudy (anonymous):

does it help to know that \(\frac{6}{30}=\frac{1}{5}\)

OpenStudy (anonymous):

So: |dw:1430272517950:dw| @nizhulei

OpenStudy (anonymous):

yikes a roni

OpenStudy (anonymous):

\[\frac{4\sqrt6}{\sqrt{30}}=\frac{4}{\sqrt5}\] is a good start

OpenStudy (anonymous):

My thoughts exactly. :/

OpenStudy (anonymous):

then \[\frac{4}{\sqrt5}\times \frac{\sqrt5}{\sqrt5}=\frac{4\sqrt5}{5}\]
