Answer 1

$Bom \: \: dia!!! \\ \\ \frac{ \sqrt{2} }{7 \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \\ \frac{ \sqrt{6} }{7 \times 3} = \\ \frac{ \sqrt{6} }{21} \\ \\ Espero \: \: ter \: \: ajudado! :)$

Answer 2

$\frac{ \sqrt{2} }{7 \sqrt{3} } = \frac{ \sqrt{2} }{7 \sqrt{3} } \times \frac{7 \sqrt{3} }{7 \sqrt{3} } = \frac{7 \sqrt{6} }{147} = \frac{ \sqrt{6} }{21}$
