Answer 1

$2 \sqrt{24} \times( \frac{3}{ \sqrt{6} } - \frac{ \sqrt{2} }{ \sqrt{3} } )$

$2 \sqrt{24} \times ( \frac{3 \sqrt{3} }{ \sqrt{18} } - \frac{ \sqrt{12} }{ \sqrt{18} } ) \\ 2 \sqrt{24} \times ( \frac{3 \sqrt{3} }{ \sqrt{18} } - \frac{2 \sqrt{3} }{ \sqrt{18} } ) \\ 2 \sqrt{24} \times \frac{ \sqrt{3} }{ \sqrt{18} } \\ 2 \times 2 \sqrt{6} \times \frac{ \sqrt{3} }{ \sqrt{18} } \\ 4 \sqrt{6} \times \frac{ \sqrt{3} }{3 \sqrt{2} } \\ \frac{4 \sqrt{18} }{3 \sqrt{2} } \\ \\ \frac{4 \sqrt{9} }{3} \\ \frac{4 \times 3}{3} \\ \frac{12}{3} \\ 4$
