POR FAVOR ME AJUDA ​

Answer 1

Resposta:

$\frac{3}{ \sqrt{2} } = \frac{3}{ \sqrt{2} } . \frac{ \sqrt{2} }{raiz de 2} = \frac{3 \sqrt{2} }{( \sqrt[2]{2}) {}^{2} } = \frac{3 \sqrt{2} }{2}$

$\frac{1}{ \sqrt{3} } = \frac{1}{ \sqrt{3} }. \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{1 \sqrt{3} }{( \sqrt[2]{3}) {}^{2} } = \frac{1 \sqrt{3} }{3}$

$\frac{2}{ \sqrt{3} } = \frac{2}{ \sqrt{3} }. \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{2 \sqrt{3} }{( \sqrt[2]{3}) {}^{2} } = \frac{2 \sqrt{3} }{ 3 }$

$\frac{5}{ \sqrt{7} } = \frac{5}{ \sqrt{7} }. \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{5 \sqrt{7} }{( \sqrt[2]{7}) {}^{2} } = \frac{5 \sqrt{7} }{7}$
