\[\frac{ 4\sqrt6 }{ \sqrt{30} } \times \frac{ \sqrt{30} }{ \sqrt{30} }\] \[\frac{ 4\sqrt6 (\sqrt{30}) }{ \sqrt{30}\times \sqrt{30} }\] \[\frac{ 4\sqrt{180} }{ 30 }\] \[\frac{ 24\sqrt5 }{ 30 }\] \[\frac{ 4\sqrt5 }{ 5 }\]

okay....the simplest way to expand is to go by this... \[(a+b)^2=a^2+2ab+b^2\]

It also says to justify each step? Does that mean I have to explain each step?

using that, \[(2\sqrt5+3\sqrt7)^2=(2\sqrt5)^2+2(2\sqrt5)(3\sqrt7)+(3\sqrt7)^2\]
