\frac{d}{d x} (\frac{5}{x + 3})

- \frac{5}{( x + 3 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{5}{x + 3})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{1}{x + 3})

Apply exponent rule:

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

= 5 \frac{d}{d x} ((x + 3)^{- 1})

Apply the chain rule:

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

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

\frac{d}{d x} (x + 3) = 1

= 5 (- \frac{1}{( x + 3 ) ^{2}} \cdot 1)

Simplify

5 (- \frac{1}{( x + 3 ) ^{2}} \cdot 1) : - \frac{5}{( x + 3 ) ^{2}}

= - \frac{5}{( x + 3 ) ^{2}}

6 t

\int (2 x + 5)^{3} d x

\int \frac{1}{x 4 - 9 x ^{2}} d x

f (x) = 10 - e^{x}, at x = 0

(\frac{1}{t + 1})^{^{'}}
