Answer 1

Answer:

1 ×2-root 3

_____________

2+root3 ×2-root3

2-root3

______

4-3

2-root 3 is the Answer

Answer 2

Answer⤵️

Given:

$\huge\frac{1}{2 + \sqrt{3} }$

On rationalisation,

$= \frac{1}{2 + \sqrt{3} } = \frac{2 - \sqrt{3} }{2 - \sqrt{3} }$

$= \frac{2 - \sqrt{3} }{ {(2)}^{2} - \sqrt{ {3}^{2} } }$

$= \frac{2 - \sqrt{3} }{4 - 3}$

$= \frac{2 - \sqrt{3} }{1}$

$= 2 - \sqrt{3}$

Hope this helps!
