The first derivative [src]
     4       
5*log (x + 5)
-------------
    x + 5    
$$\frac{5 \log{\left(x + 5 \right)}^{4}}{x + 5}$$
The second derivative [src]
     3                        
5*log (5 + x)*(4 - log(5 + x))
------------------------------
                  2           
           (5 + x)            
$$\frac{5 \left(4 - \log{\left(x + 5 \right)}\right) \log{\left(x + 5 \right)}^{3}}{\left(x + 5\right)^{2}}$$
The third derivative [src]
      2        /       2                      \
10*log (5 + x)*\6 + log (5 + x) - 6*log(5 + x)/
-----------------------------------------------
                           3                   
                    (5 + x)                    
$$\frac{10 \left(\log{\left(x + 5 \right)}^{2} - 6 \log{\left(x + 5 \right)} + 6\right) \log{\left(x + 5 \right)}^{2}}{\left(x + 5\right)^{3}}$$
