Question

Q simply by rational 7+3root5 diveded by 7-3root5​

Answer 1

$\frac{7 + 3 \sqrt{5} }{7 - 3 \sqrt{5} } \\ \\ \frac{ {(7 + 3 \sqrt{5} )}^{2} }{ {(7)}^{2} - {(3 \sqrt{5} )}^{2} } \\ \\ \frac{49 + 45 + 42 \sqrt{5} }{49 - 45} \\ \\ \frac{94 + 42 \sqrt{5} }{4} \\ \\ \frac{2(47 + 21 \sqrt{5} )}{4} \\ \\ \frac{47 + 21 \sqrt{5} }{2}$
