Detail solution

Let $u = 3 x$ .
$\frac{d}{d u} 2^{u} = 2^{u} \log{\left(2 \right)}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} 3 x$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $3$
The result of the chain rule is:

$3 \cdot 2^{3 x} \log{\left(2 \right)}$
Now simplify:

$3 \cdot 8^{x} \log{\left(2 \right)}$

The answer is:

$3 \cdot 8^{x} \log{\left(2 \right)}$
