Answer 1

Explicação passo-a-passo:

a )

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

$\sf \frac{7}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = > \textcolor{yellow}{ \frac{7 \sqrt{2} }{2}}$

b )

$\sf \frac{6}{ \sqrt{6} }$

$\sf \frac{6}{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} }$

$\sf \frac{6 \sqrt{6} }{6} = > \textcolor{yellow}{\sqrt{6}}$

c )

$\sf \frac{20}{2 \sqrt{2} }$

$\sf \frac{10}{ \sqrt{2} }$

$\sf \frac{10}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = > \frac{10 \sqrt{2} }{2} = > \textcolor{yellow}{5 \sqrt{2}}$
