derivative of x^9ln(5x)

Solution

\frac{d}{d x} (x^{9} ln (5 x))

Solution

9 x^{8} ln (5 x) + x^{8}

Solution steps

\frac{d}{d x} (x^{9} ln (5 x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{9}, g = ln (5 x)

= \frac{d}{d x} (x^{9}) ln (5 x) + \frac{d}{d x} (ln (5 x)) x^{9}

\frac{d}{d x} (x^{9}) = 9 x^{8}

\frac{d}{d x} (ln (5 x)) = \frac{1}{x}

= 9 x^{8} ln (5 x) + \frac{1}{x} x^{9}

\frac{1}{x} x^{9} = x^{8}

= 9 x^{8} ln (5 x) + x^{8}
