responda a questao da foto urgente e pra hj​

Answer 1

Resposta:

$\boxed{\boxed{\dfrac{\sqrt{2} }{6}}}$

Explicação passo-a-passo:

$\dfrac{2}{3\sqrt{8} } =\dfrac{\sqrt{8} }{\sqrt{8} } =\dfrac{2\sqrt{8} }{3\sqrt{64} } =\dfrac{2\sqrt{8} }{3.8} =\dfrac{2\sqrt{8} }{24}=\dfrac{\sqrt{8} }{12}=\dfrac{2\sqrt{2} }{12}=\boxed{\dfrac{\sqrt{2} }{6} }$

Answer 2

Resposta:

$\frac{2}{3 \sqrt{8} } = \frac{2}{6 \sqrt{2} } = \frac{1}{3 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \\ \\ = \frac{1 \sqrt{2} }{3 \sqrt{2} \sqrt{2} } = \frac{ \sqrt{2} }{3 \times 2} = \frac{ \sqrt{2} }{6}$
