Detail solution
  1. Don't know the steps in finding this derivative.

    But the derivative is

    xx2(log(x)+1)x^{\frac{\sqrt{x}}{2}} \left(\log{\left(\sqrt{x} \right)} + 1\right)

  2. Now simplify:

    xx2(log(x)+2)2\frac{x^{\frac{\sqrt{x}}{2}} \left(\log{\left(x \right)} + 2\right)}{2}


The answer is:

xx2(log(x)+2)2\frac{x^{\frac{\sqrt{x}}{2}} \left(\log{\left(x \right)} + 2\right)}{2}
