Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{(\sqrt{7} + \sqrt{6}).(\sqrt{7} - \sqrt{6})}$

$\mathsf{(\sqrt{7})^2 - \sqrt{7}.\sqrt{6} + \sqrt{7}.\sqrt{6} - (\sqrt{6})^2}$

$\mathsf{(\sqrt{7})^2 - (\sqrt{6})^2}$

$\mathsf{7 - 6}$

$\boxed{\boxed{\mathsf{(\sqrt{7} + \sqrt{6}).(\sqrt{7} - \sqrt{6}) = 1}}}$
