Answer 1

Hey friend,
Here is the answer you were looking for:
$\frac{1}{2 + \sqrt{3} } \\ \\ = \frac{1}{2 + \sqrt{3} } \times \frac{2 - \sqrt{3} }{2 - \sqrt{3} } \\ \\ = \frac{2 - \sqrt{3} }{( {2})^{2} - ( { \sqrt{3} })^{2} } \\ \\ = \frac{2 - \sqrt{3} }{4 - 3} \\ \\ = 2 - \sqrt{3}$

Hope my answer would be helpful to you!!!

And if helpful, then please mark as brainliest.
