The solution

You have entered [src]
   x
x*2 
$$2^{x} x$$
x*2^x
Detail solution
  1. Apply the product rule:

    ; to find :

    1. Apply the power rule: goes to

    ; to find :

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
 x      x       
2  + x*2 *log(2)
$$2^{x} x \log{\left(2 \right)} + 2^{x}$$
The second derivative [src]
 x                      
2 *(2 + x*log(2))*log(2)
$$2^{x} \left(x \log{\left(2 \right)} + 2\right) \log{\left(2 \right)}$$
The third derivative [src]
 x    2                  
2 *log (2)*(3 + x*log(2))
$$2^{x} \left(x \log{\left(2 \right)} + 3\right) \log{\left(2 \right)}^{2}$$
