Answer 1

$\frac{3 \sqrt{2} }{2 \sqrt{6} } = \frac{3 \sqrt{2}.2 \sqrt{6} }{2 \sqrt{6}.2 \sqrt{6} } = \frac{6 \sqrt{18} }{24} = \frac{ \sqrt{18} }{4} \\ \\ \frac{ \sqrt{7} + 35 }{ \sqrt{7} } = \frac{( \sqrt{7} + 35). \sqrt{7} }{ \sqrt{7}. \sqrt{7} } = \frac{7 + 35 \sqrt{7} }{7} \\ \\ \frac{ \sqrt{6} - 12 }{2 \sqrt{6} } = \frac{( \sqrt{6} - 12).2 \sqrt{6}}{2 \sqrt{6}.2 \sqrt{6}} = \frac{6 - 24 \sqrt{6} }{24}$

$\frac{3 \sqrt{21} + \sqrt{7} }{3 \sqrt{3} } = \frac{(3 \sqrt{21} + \sqrt{7}).3 \sqrt{3} }{3 \sqrt{3}.3 \sqrt{3} } = \frac{9 \sqrt{63} + 3 \sqrt{21} }{27}$
