log(5*x - 3)
Detail solution
  1. Let u=5x3u = 5 x - 3.

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

  3. Then, apply the chain rule. Multiply by ddx(5x3)\frac{d}{d x} \left(5 x - 3\right):

    1. Differentiate 5x35 x - 3 term by term:

      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

      2. The derivative of the constant 3-3 is zero.

      The result is: 55

    The result of the chain rule is:

    55x3\frac{5}{5 x - 3}

  4. Now simplify:

    55x3\frac{5}{5 x - 3}


The answer is:

55x3\frac{5}{5 x - 3}
