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

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

Solution steps

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

Apply exponent rule:

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

(1 + \frac{3}{x})^{x} = e^{x l n (1 + \frac{3}{x})}

= \frac{d}{d x} (e^{x l n (1 + \frac{3}{x})})

Apply the chain rule:

e^{x l n (1 + \frac{3}{x})} \frac{d}{d x} (x ln (1 + \frac{3}{x}))

= e^{x l n (1 + \frac{3}{x})} \frac{d}{d x} (x ln (1 + \frac{3}{x}))

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

= e^{x l n (1 + \frac{3}{x})} (ln (1 + \frac{3}{x}) - \frac{3}{x + 3})

e^{x l n (1 + \frac{3}{x})} = (1 + \frac{3}{x})^{x}

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