Derivative of log(x+5)^5-5*x

The solution

You have entered [src]

   5             
log (x + 5) - 5*x

$$- 5 x + \log{\left(x + 5 \right)}^{5}$$

log(x + 5)^5 - 5*x

Detail solution

Differentiate $- 5 x + \log{\left(x + 5 \right)}^{5}$ term by term:
1. Let $u = \log{\left(x + 5 \right)}$ .
2. Apply the power rule: $u^{5}$ goes to $5 u^{4}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x + 5 \right)}$ :
  1. Let $u = x + 5$ .
  2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + 5\right)$ :
    1. Differentiate $x + 5$ term by term:
      1. Apply the power rule: $x$ goes to $1$
      2. The derivative of the constant $5$ is zero.
      The result is: $1$
    The result of the chain rule is:
    
    $\frac{1}{x + 5}$
  The result of the chain rule is:
  
  $\frac{5 \log{\left(x + 5 \right)}^{4}}{x + 5}$
4. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $-5$
The result is: $-5 + \frac{5 \log{\left(x + 5 \right)}^{4}}{x + 5}$
Now simplify:

$\frac{5 \left(- x + \log{\left(x + 5 \right)}^{4} - 5\right)}{x + 5}$

The answer is:

$\frac{5 \left(- x + \log{\left(x + 5 \right)}^{4} - 5\right)}{x + 5}$
