Answer 1

Ответ:

$y = \frac{ \sqrt{x} \times \sqrt[7]{ {x}^{2} } }{ \sqrt[3]{x} } - \frac{ {x}^{3} }{ \sqrt[5]{ {x}^{3} } } = \\ = \frac{ {x}^{ \frac{1}{2} } \times {x}^{ \frac{2}{7} } }{ {x}^{ \frac{1}{3} } } - \frac{ {x}^{3} }{ {x}^{ \frac{3}{5} } } = \\ = {x}^{ \frac{1}{2} + \frac{2}{7} - \frac{1}{3} } - {x}^{3 - \frac{3}{5} } = {x}^{ \frac{21 + 6 - 14}{42} } - {x}^{ \frac{12}{5} } = \\ = {x}^{ \frac{13}{42} } - {x}^{ \frac{12}{5} }$

$y' = \frac{13}{42} {x}^{ \frac{13}{42} - 1 } - \frac{12}{5} {x}^{ \frac{12}{5} - 1} = \\ = \frac{13}{42} {x}^{ - \frac{29}{42} } - \frac{12}{5} {x}^{ \frac{7}{5} } = \\ = \frac{13}{42 \sqrt[42]{ {x}^{29} } } - \frac{12}{5x \sqrt[5]{ {x}^{2} } }$
