$(3 x^{5}) {(6 x^{4} + x)}^{4}$

Step 1

Since $3$ is constant with respect to $x$ , the derivative of $(3 x^{5}) {(6 x^{4} + x)}^{4}$ with respect to $x$ is $3 \frac{d}{d x} [(x^{5}) {(6 x^{4} + x)}^{4}]$ .

$3 \frac{d}{d x} [(x^{5}) {(6 x^{4} + x)}^{4}]$

Step 2

Differentiate using the Product Rule which states that $\frac{d}{d x} [f (x) g (x)]$ is $f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where $f (x) = x^{5}$ and $g (x) = {(6 x^{4} + x)}^{4}$ .

$3 (x^{5} \frac{d}{d x} [{(6 x^{4} + x)}^{4}] + {(6 x^{4} + x)}^{4} \frac{d}{d x} [x^{5}])$

Step 3

Differentiate using the chain rule, which states that $\frac{d}{d x} [f (g (x))]$ is $f' (g (x)) g' (x)$ where $f (x) = x^{4}$ and $g (x) = 6 x^{4} + x$ .
