Answer 1

........ Hey mate .........

$\frac{3 - \sqrt{5} }{3 - \sqrt{5} } \\ \\ = \geqslant rationalisaing \: it \: \\ \\ = \geqslant \frac{3 - \sqrt{5} }{3 - \sqrt{5} } \times \frac{3 + \sqrt{5} }{3 + \sqrt{5} } \\ \\ = \geqslant using \: identity \: \\ \\ = \geqslant \frac{(3) {}^{2} - ( \sqrt{5) {}^{2} } }{(3) {}^{2} - ( \sqrt{5) {}^{2} } } \\ \\ = \geqslant \frac{9 - 5}{9 - 5} \\ \\ = \geqslant \frac{4}{4} \\ \\ = \geqslant 1$
