derivative of

- \frac{5}{x ^{4}}

\frac{20}{x ^{5}}

Solution steps

\frac{d}{d x} (- \frac{5}{x ^{4}})

Take the constant out:

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

= - 5 \frac{d}{d x} (\frac{1}{x ^{4}})

Apply exponent rule:

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

= - 5 \frac{d}{d x} (x^{- 4})

Apply the Power Rule:

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

= - 5 (- 4 x^{- 4 - 1})

Simplify

- 5 (- 4 x^{- 4 - 1}) : \frac{20}{x ^{5}}

= \frac{20}{x ^{5}}

x \to - 1 lim (x^{2} - 3 x)

\int \frac{4 x}{1} d x

\frac{\partial}{\partial z} (y + z)

f (x) = 2 x + x

\frac{d}{d x} (sin (x^{2} + 3 x + 1))
