Here the denominator is (1 - √7) so in order to rationalise , we will multiply and divide by the opposite sign i,e ( 1 + √7)
As we multiply and divide simultaneously , it doesn't effect the original value.
So we have,
\begin{gathered} = > \frac{1}{1 - \sqrt{7} } \times \frac{1 + \sqrt{7} }{1 + \sqrt{7} } \\ \\ = \frac{1 + \sqrt{7} }{1 - 7} = \frac{1 + \sqrt{7} }{ - 6} \\ \\ = \frac{ - 1 - \sqrt{7} }{6} \end{gathered}
=>
