[tex](\frac{1}{ \sqrt{3} } + \frac{1}{ \sqrt{6} } ) \times \frac{4}{ \sqrt{2} } = (\frac{ \sqrt{2} }{ \sqrt{6} } + \frac{1}{ \sqrt{6} } ) \times \frac{4}{ \sqrt{2} } = \frac{ \sqrt{2} + 1}{ \sqrt{6} } \times \frac{4}{ \sqrt{2} } = \frac{4( \sqrt{2} + 1 )}{2 \sqrt{3} } = \frac{4( \sqrt{2} + 1 )}{2 \sqrt{3} } = \frac{2( \sqrt{2} + 1 )}{ \sqrt{3} }= \frac{2 \sqrt{3}( \sqrt{2} + 1) }{3} [/tex]
