derivative of

\frac{3}{r ^{3}}

- \frac{9}{r ^{4}}

Solution steps

\frac{d}{d r} (\frac{3}{r ^{3}})

Take the constant out:

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

= 3 \frac{d}{d r} (\frac{1}{r ^{3}})

Apply exponent rule:

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

= 3 \frac{d}{d r} (r^{- 3})

Apply the Power Rule:

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

= 3 (- 3 r^{- 3 - 1})

Simplify

3 (- 3 r^{- 3 - 1}) : - \frac{9}{r ^{4}}

= - \frac{9}{r ^{4}}

\frac{d y}{d x} = \frac{1 - y ^{2}}{x}

n = 6 \sum \infty \frac{5 ^{n}}{1 0 ^{n}}

\int \frac{tan ^{3} ( \frac{2}{z} )}{z ^{2}}

\frac{d y}{d x} + x y = y^{4}

\int \frac{x + 9}{x ^{2} + 9} d x
