$\frac{1}{ \sqrt{7} - 2 } \\ \\ = \frac{1}{ \sqrt{7} - 2 } \times \frac{ \sqrt{7} + 2}{ \sqrt{7} + 2 } \\ \\ = \frac{ \sqrt{7} + 2 }{( \sqrt{7) {}^{2} } - (2) {}^{2} } \\ \\ = \frac{ \sqrt{7} + 2 }{7 - 4} \\ \\ = \frac{ \sqrt{7} + 2}{3} \\ \\ therefore \: the \: answer \: is \: \\ \frac{ \sqrt{7} + 2}{3}$
