Piecewise:

The solution

You have entered [src]
log(3*x)
$$\log{\left(3 x \right)}$$
log(3*x)
Detail solution
  1. Let .

  2. The derivative of is .

  3. Then, apply the chain rule. Multiply by :

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: goes to

      So, the result is:

    The result of the chain rule is:
