Answer 2

Given:

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

Solution:

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

Rationalise,

$\implies \frac{2}{ \sqrt{3} - 1} \times \frac{ \sqrt{3 + 1} }{ \sqrt{3 + 1} } \implies \frac{2( \sqrt{3} + 1}{ { \sqrt{3} }^{2} - {1}^{2} }$

→(a+b)(a-b)=a²-b²

$\implies \: \frac{2( \sqrt{3} + 1)}{3 - 1} \implies \: \frac{2( \sqrt{3} + 1)}{3 - 1} \\ \\ \implies \: \sqrt{3} + 1$
