\frac{d}{d x} (\frac{9}{x ^{4}})

- \frac{36}{x ^{5}}

Solution steps

\frac{d}{d x} (\frac{9}{x ^{4}})

Take the constant out:

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

= 9 \frac{d}{d x} (\frac{1}{x ^{4}})

Apply exponent rule:

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

= 9 \frac{d}{d x} (x^{- 4})

Apply the Power Rule:

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

= 9 (- 4 x^{- 4 - 1})

Simplify

9 (- 4 x^{- 4 - 1}) : - \frac{36}{x ^{5}}

= - \frac{36}{x ^{5}}

3 x^{2}, - 3 x + 6, - 4, 2

x \to 0 + lim (\frac{x + 92}{x})

\frac{d}{d x} (- \frac{a}{x})

\int \frac{e ^{x}}{1 + e ^{x}} d x

\int x^{9} x^{5} + 3 d x
