Best ResponseYou've already chosen the best response.1\[\frac{ 4\sqrt6 }{ \sqrt{30} } \times \frac{ \sqrt{30} }{ \sqrt{30} }\] \[\frac{ 4\sqrt6 (\sqrt{30}) }{ \sqrt{30}\times \sqrt{30} }\] \[\frac{ 4\sqrt{180} }{ 30 }\] \[\frac{ 24\sqrt5 }{ 30 }\] \[\frac{ 4\sqrt5 }{ 5 }\]

Best ResponseYou've already chosen the best response.1okay....the simplest way to expand is to go by this... \[(a+b)^2=a^2+2ab+b^2\]

Best ResponseYou've already chosen the best response.0It also says to justify each step? Does that mean I have to explain each step?

Best ResponseYou've already chosen the best response.1using that, \[(2\sqrt5+3\sqrt7)^2=(2\sqrt5)^2+2(2\sqrt5)(3\sqrt7)+(3\sqrt7)^2\]

Best ResponseYou've already chosen the best response.1\[(2^2(\sqrt5)^2)+4\sqrt5(3\sqrt7)+(3^2(\sqrt7)^2\] \[20 + 12\sqrt{35}+63\] \[83+12\sqrt{35}\]
