x^n
Detail solution
  1. Apply the power rule: goes to

  2. Now simplify:


The answer is:

The first derivative [src]
   n
n*x 
----
 x  
$$\frac{n x^{n}}{x}$$
The second derivative [src]
   n         
n*x *(-1 + n)
-------------
       2     
      x      
$$\frac{n x^{n} \left(n - 1\right)}{x^{2}}$$
The third derivative [src]
   n /     2      \
n*x *\2 + n  - 3*n/
-------------------
          3        
         x         
$$\frac{n x^{n} \left(n^{2} - 3 n + 2\right)}{x^{3}}$$
