i)

$4 \sqrt{48} - \frac{5}{2} \sqrt{ \frac{1}{3}} + 6 \sqrt{3} \\ \\ 16 \sqrt{3} - \frac{5}{2} \sqrt{ \frac{1}{3} } + 6 \sqrt{3} \\ \\ 22 \sqrt{3} - \frac{5}{2 \sqrt{3} } \\ \\ \frac{132 - 5}{2 \sqrt{3} } = \frac{127}{2 \sqrt{3} }$

ii)
$\sqrt{63} + \sqrt{28} - \sqrt{175} \\ \\ 3 \sqrt{7} + 2 \sqrt{7} - 5 \sqrt{7} = 0$

iii)
$\sqrt{8} + \sqrt{128} - \sqrt{50} \\ \\ 2 \sqrt{2} + 8 \sqrt{2} - 5 \sqrt{2} \\ \\ 5 \sqrt{2}$
