We have,
\huge\purple{\orange{ \mapsto } \frac{1}{ \sqrt{3} + 1} }

\huge\blue{ = \frac{1}{ \sqrt{3} + 1} \times \frac{ \sqrt{3} - 1}{ \sqrt{3} - 1} }

\huge\blue{ = \frac{ \sqrt{3} - 1}{( \sqrt{3} + 1)( \sqrt{3} - 1)} }

\huge\blue{ = \frac{ \sqrt{3} - 1}{ {( \sqrt{3} )}^{2} - {(1)}^{2} } }

\huge\blue{ = \frac{ \sqrt{3} - 1}{3 - 1} }

\huge\blue{ = \frac{ \sqrt{3} - 1}{2} }
