what it is right or not

if yes then like

Answer 2

$\frac{2 + \sqrt{3} }{2 - \sqrt{3} } \\ = \frac{2 + \sqrt{3} }{2 - \sqrt{3} } \times \frac{2 + \sqrt{3} }{2 + \sqrt{3} } \\ = \frac{ ({2 + \sqrt{3} )}^{2} }{ {2}^{2} - { \sqrt{3} }^{2} } \\ = \frac{4 + 3 + 4 \sqrt{3} }{4 - 3} \\ = \frac{7 + 4 \sqrt{3} }{1} \\ = 7 + 4 \sqrt{3}$
