Answer 2

Answer:

$\frac{ \sqrt{2} + \sqrt{7} }{ \sqrt{2} - \sqrt{7} } \\ \frac{ \sqrt{2} + \sqrt{7} }{ \sqrt{2} - \sqrt{7} } \times \frac{ \sqrt{2} + \sqrt{7} }{ \sqrt{2} + \sqrt{7} } \\ \frac{( \sqrt{2)} {}^{2} + ( \sqrt{7)} {}^{2} }{( \sqrt{2)} {}^{2} - ( \sqrt{7)} {}^{2} } \\ \frac{2 + 7}{2 - 7} = \frac{9}{ - 5}$
