Answer 2

$\frac{7 + \sqrt{5} }{7 - \sqrt{5} } \\ \\ = \geqslant \frac{7 + \sqrt{5} }{7 - \sqrt{5} } \times \frac{7 + \sqrt{5} }{7 + \sqrt{5} } \\ \\ = \geqslant \frac{(7 + \sqrt{5}) {}^{2} }{ {7}^{2} - { \sqrt{5} }^{2} } \\ \\ = \geqslant \frac{49 + 5 + 14 \sqrt{5} }{49 - 5} \\ \\ = \geqslant \frac{54 + 14 \sqrt{5} }{44}$
