Answer 1

$\huge \pink{ \boxed{ \sf{ \red{Answer:-}}}}$

According to question:

$= \frac{1}{ \sqrt{7} - \sqrt{6} }$

$= \frac{1}{ \sqrt{7} - \sqrt{6} } \times \frac{ \sqrt{7} + \sqrt{6} }{ \sqrt{7} + \sqrt{6} }$

$= \frac{ \sqrt{7} + \sqrt{6} }{ {( \sqrt{7} )}^{2} - {( \sqrt{6}) }^{2} }$

$= \frac{ \sqrt{7} + \sqrt{6} }{7 - 6}$

$= \sqrt{7} + \sqrt{6}$
