\frac{d}{d x} (\frac{- 20}{( 2 + x ) ^{2}})

\frac{40}{( 2 + x ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{- 20}{( 2 + x ) ^{2}})

Simplify

\frac{- 20}{( 2 + x ) ^{2}} : - \frac{20}{( 2 + x ) ^{2}}

= \frac{d}{d x} (- \frac{20}{( 2 + x ) ^{2}})

Take the constant out:

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

= - 20 \frac{d}{d x} (\frac{1}{( 2 + x ) ^{2}})

Apply exponent rule:

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

= - 20 \frac{d}{d x} ((2 + x)^{- 2})

Apply the chain rule:

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

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

\frac{d}{d x} (2 + x) = 1

= - 20 (- \frac{2}{( 2 + x ) ^{3}} \cdot 1)

Simplify

- 20 (- \frac{2}{( 2 + x ) ^{3}} \cdot 1) : \frac{40}{( 2 + x ) ^{3}}

= \frac{40}{( 2 + x ) ^{3}}

x^{2} - 11, 10 x

(x, y) \to (0, 0) lim (\frac{e ^{x y} - 1}{x y})

\frac{\partial}{\partial x} (x^{4} + 3 y^{3})

x \to 1 lim (x^{3} - 3 x + 2)

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