Question

у=-1/х^2
У=3/х^4/3
Найдите производную функции​

Answer 1

Ответ:

$1)y = - \frac{1}{ {x}^{2} } = - {x}^{ - 2}$

$y' = - ( - 2) \times {x}^{ - 3} = \frac{2}{ {x}^{3} }$

$2)y = \frac{3}{ {x}^{ \frac{4}{3} } } = 3 {x}^{ - \frac{4}{3} }$

$y' = 3 \times ( - \frac{4}{3} ) {x}^{ - \frac{4}{3} - 1} = - 4 {x}^{ - \frac{7}{3} } = \\ = - \frac{4}{ {x}^{2} \sqrt[3]{x} }$
