 2*x - 4           
E        + 2*log(x)
e2x4+2log(x)e^{2 x - 4} + 2 \log{\left(x \right)}
E^(2*x - 4) + 2*log(x)
Detail solution
  1. Differentiate e2x4+2log(x)e^{2 x - 4} + 2 \log{\left(x \right)} term by term:

    1. Let u=2x4u = 2 x - 4.

    2. The derivative of eue^{u} is itself.

    3. Then, apply the chain rule. Multiply by ddx(2x4)\frac{d}{d x} \left(2 x - 4\right):

      1. Differentiate 2x42 x - 4 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 4-4 is zero.

        The result is: 22

      The result of the chain rule is:

      2e2x42 e^{2 x - 4}

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

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

      So, the result is: 2x\frac{2}{x}

    The result is: 2e2x4+2x2 e^{2 x - 4} + \frac{2}{x}

  2. Now simplify:

    2(xe2x4+1)x\frac{2 \left(x e^{2 x - 4} + 1\right)}{x}


The answer is:

2(xe2x4+1)x\frac{2 \left(x e^{2 x - 4} + 1\right)}{x}
