Answer 2

$= \ \textgreater \ \frac{5 + \sqrt{3} }{7 + 4 \sqrt{3} }$

$= \ \textgreater \ \frac{(5 + \sqrt{3})(7 - 4 \sqrt{3} ) }{(7 + 4 \sqrt{3})(7 - 4 \sqrt{3}) }$

$= \ \textgreater \ \frac{ 5*7 - 5 * 4 \sqrt{3} + \sqrt{3} * 7 - \sqrt{3} * 4 \sqrt{3}}{(7)^2 - (4 \sqrt{3})^2 }$

$= \ \textgreater \ \frac{35 - 20 \sqrt{3} + 7 \sqrt{3} - 12 }{49 - 48}$

$= \ \textgreater \ \frac{35 - 13 \sqrt{3} - 12 }{1}$

$= \ \textgreater \ 23 - 13 \sqrt{3}$


Hope this helps!
