\/ x *log(x) + x
$$\sqrt{x} \log{\left(x \right)} + x$$
sqrt(x)*log(x) + x
Detail solution
  1. Differentiate term by term:

    1. Apply the product rule:

      ; to find :

      1. Apply the power rule: goes to

      ; to find :

      1. The derivative of is .

      The result is:

    2. Apply the power rule: goes to

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
      1      log(x)
1 + ----- + -------
      ___       ___
    \/ x    2*\/ x 
$$1 + \frac{\log{\left(x \right)}}{2 \sqrt{x}} + \frac{1}{\sqrt{x}}$$
The second derivative [src]
-log(x) 
--------
    3/2 
 4*x    
$$- \frac{\log{\left(x \right)}}{4 x^{\frac{3}{2}}}$$
The third derivative [src]
-2 + 3*log(x)
-------------
       5/2   
    8*x      
$$\frac{3 \log{\left(x \right)} - 2}{8 x^{\frac{5}{2}}}$$
