derivative of

y = \frac{81}{x ^{4}}

- \frac{324}{x ^{5}}

Solution steps

\frac{d}{d x} (\frac{81}{x ^{4}})

Take the constant out:

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

= 81 \frac{d}{d x} (\frac{1}{x ^{4}})

Apply exponent rule:

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

= 81 \frac{d}{d x} (x^{- 4})

Apply the Power Rule:

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

= 81 (- 4 x^{- 4 - 1})

Simplify

81 (- 4 x^{- 4 - 1}) : - \frac{324}{x ^{5}}

= - \frac{324}{x ^{5}}

f (x) = x^{4} - 4 x^{2} + 7, at x = 1

\frac{d}{d x} (\frac{e ^{8 x}}{3 x ^{4}})

\int (3 x - 6 x) d x

x \to 0 lim (\frac{2 x ^{2} - x}{x})

y = (x)^{x}
