log(2*x - 6/5)
log(2x65)\log{\left(2 x - \frac{6}{5} \right)}
log(2*x - 6/5)
Detail solution
  1. Let u=2x65u = 2 x - \frac{6}{5}.

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

  3. Then, apply the chain rule. Multiply by ddx(2x65)\frac{d}{d x} \left(2 x - \frac{6}{5}\right):

    1. Differentiate 2x652 x - \frac{6}{5} 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: 22

      2. The derivative of the constant 65- \frac{6}{5} is zero.

      The result is: 22

    The result of the chain rule is:

    22x65\frac{2}{2 x - \frac{6}{5}}

  4. Now simplify:

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


The answer is:

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