derivative of

- \frac{7}{4 x}

\frac{7}{4 x ^{\frac{5}{4}}}

Solution steps

\frac{d}{d x} (- \frac{7}{4 x})

Take the constant out:

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

= - 7 \frac{d}{d x} (\frac{1}{4 x})

Apply exponent rule:

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

= - 7 \frac{d}{d x} (x^{- \frac{1}{4}})

Apply the Power Rule:

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

= - 7 (- \frac{1}{4} x^{- \frac{1}{4} - 1})

Simplify

- 7 (- \frac{1}{4} x^{- \frac{1}{4} - 1}) : \frac{7}{4 x ^{\frac{5}{4}}}

= \frac{7}{4 x ^{\frac{5}{4}}}

\int \frac{x ^{4}}{8 - x ^{5}} d x

(x + y e^{\frac{y}{x}}) d x - x e^{\frac{y}{x}} d y = 0

\int_{- 1}^{1} e^{y} - y^{2} + 6 d y

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

\int 25 x^{2} d x
