Given:-

$\star \sf \large{ \underline{ \color{violet} {\frac{1 + \sqrt{7} }{1 - \sqrt{7} }}}}$

$\sf{ :⟹\frac{1 + \sqrt{7} }{1 - \sqrt{7} }}$

$\sf{:⟹ \frac{1 + \sqrt{7 }\times 1 + \sqrt{7} }{1 - 7} }$

$\sf{:⟹ \frac{1 + 7 + 2 \sqrt{7} }{ - 6} }$

$\sf{:⟹ \frac{8 + 2 \sqrt{7} }{ - 6} }$

$\sf{ :⟹\frac{2(4 + \sqrt{7)} }{2( - 3)} }$

$\sf \huge \bold:⟹ { \underline{ \underline{ \frac{4 + \sqrt{7} }{ - 3} }}}$
