[tex] \frac{5 \sqrt{2} }{3 \sqrt{3} } = \frac{5 \sqrt{2} \times \sqrt{3} }{3 \times 3} = \frac{5 \sqrt{6} }{9} [/tex]
[tex] \frac{ \sqrt{3} }{ \sqrt{2} } = \frac{ \sqrt{3} \times \sqrt{2} }{2} = \frac{ \sqrt{6} }{2} [/tex]
[tex] \frac{5 \sqrt{6} }{9} - \frac{ \sqrt{6} }{2} = \frac{10 \sqrt{6} - 9 \sqrt{6} }{18} = \frac{ \sqrt{6} }{18} [/tex]
