Detail solution

Let $u = \log{\left(\sin^{4}{\left(5 x \right)} \right)}$ .
Apply the power rule: $u^{3}$ goes to $3 u^{2}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(\sin^{4}{\left(5 x \right)} \right)}$ :
1. Let $u = \sin^{4}{\left(5 x \right)}$ .
2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin^{4}{\left(5 x \right)}$ :
  1. Let $u = \sin{\left(5 x \right)}$ .
  2. Apply the power rule: $u^{4}$ goes to $4 u^{3}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(5 x \right)}$ :
    1. Let $u = 5 x$ .
    2. The derivative of sine is cosine:
      
      $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
    3. Then, apply the chain rule. Multiply by $\frac{d}{d x} 5 x$ :
      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: $5$
      The result of the chain rule is:
      
      $5 \cos{\left(5 x \right)}$
    The result of the chain rule is:
    
    $20 \sin^{3}{\left(5 x \right)} \cos{\left(5 x \right)}$
  The result of the chain rule is:
  
  $\frac{20 \cos{\left(5 x \right)}}{\sin{\left(5 x \right)}}$
The result of the chain rule is:

$\frac{60 \log{\left(\sin^{4}{\left(5 x \right)} \right)}^{2} \cos{\left(5 x \right)}}{\sin{\left(5 x \right)}}$
Now simplify:

$\frac{60 \log{\left(\sin^{4}{\left(5 x \right)} \right)}^{2}}{\tan{\left(5 x \right)}}$

The answer is:

\frac{60 \log{\left(\sin^{4}{\left(5 x \right)} \right)}^{2}}{\tan{\left(5 x \right)}}
