Answer 2

Answer:

$\frac{5}{2 + \sqrt{3} } \\ \\ = \frac{5}{2 + \sqrt{3} } \times \frac{2 - \sqrt{3} }{2 - \sqrt{3} } \\ \\ = \frac{5 \times (2 - \sqrt{3}) }{ {2}^{2} - { (\sqrt{3}) }^{2} } \\ \\ = \frac{10 - 5 \sqrt{3} }{4 - 3} \\ \\ = \frac{10 - 5 \sqrt{3} }{1} \\ \\ = 10 - 5 \sqrt{3} \\ \\ = 10 - (5 \times 1.732) \\ \\ = 10 - 8.66 \\ \\ = 1.34$
