Odpowiedź:
[tex]\sqrt{2}, \frac{5\sqrt{2} }{7}[/tex]
Szczegółowe wyjaśnienie:
[tex]\frac{2}{\sqrt{2} }= \frac{2}{\sqrt{2} }*\frac{\sqrt{2} }{\sqrt{2}}=\frac{2\sqrt{2} }{2}=\sqrt{2}[/tex]
[tex]\frac{10}{7\sqrt{2} } =\frac{10}{7\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2}} =\frac{10\sqrt{2} }{14}= \frac{5\sqrt{2} }{7}[/tex]
