\frac{d}{d x} (k x^{x})

k x^{x} (ln (x) + 1)

Solution steps

\frac{d}{d x} (k x^{x})

Take the constant out:

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

= k \frac{d}{d x} (x^{x})

Apply exponent rule:

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

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

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

Apply the chain rule:

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

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

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

= k e^{x l n (x)} (ln (x) + 1)

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

= k x^{x} (ln (x) + 1)
