Answer 1

hey!here is ur answer....
$\frac{4 + \sqrt{5} }{4 - \sqrt{5} } + \frac{4 - \sqrt{5} }{4 + \sqrt{5} } \\ = \frac{(4 + \sqrt{5} )(4 + \sqrt{5}) + (4 - \sqrt{5})(4 - \sqrt{5} ) }{(4 - \sqrt{5})(4 + \sqrt{5}) } \\ = \frac{ {(4 + \sqrt{5} )}^{2} + {(4 - \sqrt{5} )}^{2} }{16 - 5} \\ = \frac{16 + 5 + 8 \sqrt{5} + 16 + 5 - 8 \sqrt{5} }{11} \\ = \frac{42}{11} (answer)$
hope it helps... please mark it brainliest answer.
