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

- \frac{20}{e ^{4 x}}

Solution steps

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

Take the constant out:

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

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

Apply the chain rule:

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

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

\frac{d}{d x} (e^{x}) = e^{x}

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

Simplify

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

= - \frac{20}{e ^{4 x}}

x \to 2 lim (12 x^{2})

x \to - 2 lim (\frac{∣ x + 2 ∣}{x + 2})

\int \frac{sech ( \frac{1}{x} ) tanh ( \frac{1}{x} )}{x ^{2}} d x

\int \frac{1}{9 + t ^{2}} d t

\int 9 csc (x) d x
