Answer 2

Answer:

$\frac{1}{4 + 2 \sqrt{ 3} } \\ \\ = \frac{1}{4 + 2 \sqrt{3} } \times \frac{4 - 2 \sqrt{3} }{4 - 2 \sqrt{3} } \\ \\ = \frac{4 - 2 \sqrt{3} }{(4) ^{2} - (2 \sqrt{3}) ^{2} } \\ \\ = \frac{4 - 2 \sqrt{3} }{16 - 4 \times 3} \\ \\ = \frac{4 - 2 \sqrt{3} }{16 - 12} \\ \\ = \frac{4 - 2 \sqrt{3} }{4} \\ \\ = \frac{2(2- \sqrt{3}) }{4} \\ \\ = \frac{2 - \sqrt{3} }{2}$
