log(5*x)
Detail solution
  1. Let u=5xu = 5 x.

  2. The derivative of log(u)\log{\left(u \right)} is 1u\frac{1}{u}.

  3. Then, apply the chain rule. Multiply by ddx5x\frac{d}{d x} 5 x:

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

      1. Apply the power rule: xx goes to 11

      So, the result is: 55

    The result of the chain rule is:

    1x\frac{1}{x}


The answer is:

1x\frac{1}{x}
