[tex] \frac{5 \sqrt{3} }{ \sqrt{6} } - ( - \frac{10 \sqrt{2} }{2 \sqrt{6} }) = \frac{5 \sqrt{3} }{ \sqrt{6} } + \frac{10 \sqrt{2} }{2 \sqrt{6} } \\ \frac{5 \sqrt{18} }{6} + \frac{10 \sqrt{12} }{12} = \\ \frac{15 \sqrt{2} }{6} + \frac{20 \sqrt{3} }{12} = \\ \frac{5 \sqrt{2} }{2} + \frac{5 \sqrt{3} }{3} [/tex]
