\frac{d}{d x} (a x^{- 2})

- \frac{2 a}{x ^{3}}

Solution steps

\frac{d}{d x} (a x^{- 2})

Take the constant out:

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

= a \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= a (- 2 x^{- 2 - 1})

Simplify

a (- 2 x^{- 2 - 1}) : - \frac{2 a}{x ^{3}}

= - \frac{2 a}{x ^{3}}

y = \frac{( x + 3 )}{( x + 1 ) ^{2}}, at x = 0

\frac{\partial}{\partial x} (3 e^{x} - 5 x e^{y})

\frac{d}{d x} (\frac{2}{1 + 3 e ^{- 2 x}})

y = sin (cos (tan (π x)))

n = 1 \sum \infty \frac{4 ^{n}}{7 ^{n}}
