\frac{d}{d x} (\frac{1}{10 x ^{\frac{9}{10}}})

- \frac{9}{100 x ^{\frac{19}{10}}}

Solution steps

\frac{d}{d x} (\frac{1}{10 x ^{\frac{9}{10}}})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{10} \frac{d}{d x} (\frac{1}{x ^{\frac{9}{10}}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= \frac{1}{10} \frac{d}{d x} (x^{- \frac{9}{10}})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= \frac{1}{10} (- \frac{9}{10} x^{- \frac{9}{10} - 1})

Simplify

\frac{1}{10} (- \frac{9}{10} x^{- \frac{9}{10} - 1}) : - \frac{9}{100 x ^{\frac{19}{10}}}

= - \frac{9}{100 x ^{\frac{19}{10}}}

\int \frac{x - 11}{x ^{2} + 6 x + 25} d x

f (x) = x (7^{- 3 x})

\int \frac{x ^{2} - 7 x + 12}{x - 3} d x

y = \frac{3 x - 9}{2 x + 8}

\frac{d}{d x} (\frac{4 + ln ( 2 x )}{2020 + x})
