Answer 2

Step-by-step explanation:

$\frac{7 + 3 \sqrt{5} }{7 - 3 \sqrt{5} }$

on rationalising the denominator

$\frac{7 + 3 \sqrt{5} }{7 - 3 \sqrt{5} } \times \frac{7 + 3 \sqrt{5} }{7 + 3 \sqrt{5} }$

$\frac{ {(7 + 3 \sqrt{5)} }^{2} }{ {7}^{2} - {3 \sqrt{5} }^{2} }$

$\frac{49 + 15 + 2 \times 49 \times 15}{49 - 15}$

$\frac{1534}{34}$
