16

$y '= ( \frac{1}{ \sqrt[7]{x} } )' = ( {x}^{ - \frac{1}{7} } )' = - \frac{1}{7} {x}^{ - \frac{8}{7} } = - \frac{1}{7x \sqrt[7]{x} }$

17

$y' = ( \sqrt[7]{ {x}^{6} } ) '= ( {x}^{ \frac{6}{7} } )' = \frac{6}{7} {x}^{ - \frac{1}{7} } = \frac{6}{7 \sqrt[7]{x} }$

18

$y' = ( \sqrt[7]{ {x}^{ - 6} } ) '= ( {x}^{ - \frac{6}{7} } )' = - \frac{6}{7} {x}^{ - \frac{13}{6} } = - \frac{6}{7x \sqrt[7]{ {x}^{6} } }$
