2 sobre raiz de 7 mais raiz de 2

Answer 1

$\frac{2}{ {\sqrt{7}+ \sqrt{2} } }$

$\frac{2 \times (\sqrt{7} - \sqrt{2}) }{( \sqrt{7} + \sqrt{2}) \times ( \sqrt{7} - \sqrt{2} ) }$

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

$\frac{2 \times ( \sqrt{7} - \sqrt{2})}{7 + 2}$

$\frac{2 \times ( \sqrt{7} - \sqrt{2}) }{9}$
