Answer 2

you can split the fraction into 2 radicals
\[\frac{\sqrt{24}}{\sqrt5}\]
Get rid of radical on bottom by multiplying it by itself
\[\frac{\sqrt{24}}{\sqrt{5}}*\frac{\sqrt{5}}{\sqrt{5}} = \frac{\sqrt{24}\sqrt{5}}{5}\]

Answer 3

Finally simplify sqrt24
\[\sqrt{24} = \sqrt{4} \sqrt{6} = 2 \sqrt{6}\]
