Answer 1

Answer:

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

$\frac{ \sqrt{7} + \sqrt{6}( \sqrt{7} - \sqrt{6}) }{ { (\sqrt{7}) }^{2} - ( { \sqrt{6} }^{2} )} = \frac{ { (\sqrt{7} )}^{2} - { (\sqrt{6} )}^{2} }{7 - 6} = 1$

that's is your answer
