[tex] \frac{3}{2 \sqrt{7} } = \frac{3}{2 \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{3 \sqrt{7} }{2 \sqrt{7} \sqrt{7} } = \frac{3 \sqrt{7} }{14} [/tex]
[tex] \frac{11}{3 \sqrt{2} } = \frac{11}{3 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{11 \sqrt{2} }{3 \sqrt{2} \sqrt{2} } = \frac{11 \sqrt{2} }{6} [/tex]
