Hope u like my process
=====================

 = > \bf\frac{5 + 2 \sqrt{3} }{7 + 4 \sqrt{3} } \\ \\ = > \frac{(5 + 2 \sqrt{3}) }{(7 + 4 \sqrt{3} )} \times \frac{(7 - 4 \sqrt{3}) }{(7 - 4 \sqrt{3}) } \\ \\ = > \frac{(5 + 2 \sqrt{3} )(7 - 4 \sqrt{3} )}{ {7}^{2} - {(4 \sqrt{3}) }^{2} } \\ \\ = > \frac{(7 \times 5) + (7 \times 2 \sqrt{3}) - (5 \times 4 \sqrt{3} ) - (4 \sqrt{3} \times 2 \sqrt{3}) }{49 - 48} \\ \\ = > 35 + 14 \sqrt{3} - 20 \sqrt{3 } - 24 \\ \\ = > \bf \underline{11 - 6 \sqrt{3}}
