Step-by-step explanation:

Answer 2

Step-by-step explanation:

$\huge\underline{\underline{\ Answer}} \\ \implies \frac{1}{ \sqrt{3} - \sqrt{2} - 1 } \\ \implies \frac{1}{ \sqrt{3} - \sqrt{2} - 1 } \times \frac{ \sqrt{3} + \sqrt{2} - 1 }{ \sqrt{3} + \sqrt{2} - 1 } \\ \implies \frac{ \sqrt{3} + \sqrt{2} - 1 }{3 - 2 + 1} \\ \implies \frac{ \sqrt{3} + \sqrt{2} - 1 }{2}$
