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

\int 1 + 6 x^{\frac{1}{2}} d x

f (x) = x \cdot sin (x)

y^{^{''}} - 4 y^{^{'}} - 5 y = 0, y (1) = 0, y^{^{'}} (1) = 3

f^{^{'}} (x) = x^{2} - x

\int (4 - 3 x)^{3} d x
