derivative of

f (x) = (x + 2)^{x}

(ln (x + 2) + \frac{x}{x + 2}) (x + 2)^{x}

Solution steps

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

Apply exponent rule:

a^{b} = e^{b l n (a)}

(x + 2)^{x} = e^{x l n (x + 2)}

= \frac{d}{d x} (e^{x l n (x + 2)})

Apply the chain rule:

e^{x l n (x + 2)} \frac{d}{d x} (x ln (x + 2))

= e^{x l n (x + 2)} \frac{d}{d x} (x ln (x + 2))

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

= e^{x l n (x + 2)} (ln (x + 2) + \frac{x}{x + 2})

e^{x l n (x + 2)} = (x + 2)^{x}

= (ln (x + 2) + \frac{x}{x + 2}) (x + 2)^{x}

x \to 2 lim (x^{2} + 3 x - 8)

\int 9 + 8 x - x^{2} d x

\int x^{2} e^{11 x} d x

x \to 2 lim (3 x + 5)

\int cos^{5} (3 x) sin^{4} (3 x) d x
