\/ 2*log(5*x + 6/5)

$$\sqrt{2 \log{\left(5 x + \frac{6}{5} \right)}}$$

sqrt(2*log(5*x + 6/5))

Detail solution

Let $u = 2 \log{\left(5 x + \frac{6}{5} \right)}$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} 2 \log{\left(5 x + \frac{6}{5} \right)}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Let $u = 5 x + \frac{6}{5}$ .
  2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(5 x + \frac{6}{5}\right)$ :
    1. Differentiate $5 x + \frac{6}{5}$ term by term:
      1. The derivative of a constant times a function is the constant times the derivative of the function.
        
        Apply the power rule: $x$ goes to $1$
        
        So, the result is: $5$
      2. The derivative of the constant $\frac{6}{5}$ is zero.
      The result is: $5$
    The result of the chain rule is:
    
    $\frac{5}{5 x + \frac{6}{5}}$
  So, the result is: $\frac{10}{5 x + \frac{6}{5}}$
The result of the chain rule is:

$\frac{5 \sqrt{2}}{2 \left(5 x + \frac{6}{5}\right) \sqrt{\log{\left(5 x + \frac{6}{5} \right)}}}$
Now simplify:

$\frac{25 \sqrt{2}}{2 \left(25 x + 6\right) \sqrt{\log{\left(5 x + \frac{6}{5} \right)}}}$

The answer is:

$\frac{25 \sqrt{2}}{2 \left(25 x + 6\right) \sqrt{\log{\left(5 x + \frac{6}{5} \right)}}}$
