Как выделить куб под радикалом в данном случае?
[tex] \frac{ \sqrt{2}-1 }{ \sqrt{2}+1} * \sqrt[3]{ \frac{10+7 \sqrt{2} }{10-7 \sqrt{2} } } = \frac{( \sqrt{2}-1) *( \sqrt{2} -1) }{( \sqrt{2}+1)*( \sqrt{2} -1)} * \sqrt[3]{ \frac{10+7 \sqrt{2} }{10-7 \sqrt{2} } } = (\sqrt{2}-1 )^{2} * \sqrt[3]{ \frac{10+7 \sqrt{2} }{10-7 \sqrt{2} } }[/tex]
