$$\left(\frac{\log{\left(\sin^{2}{\left(x \right)} \right)}}{\log{\left(2 \right)}}\right)^{3}$$

(log(sin(x)^2)/log(2))^3

Detail solution

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

$\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2} \cos{\left(x \right)}}{\log{\left(2 \right)}^{3} \sin{\left(x \right)}}$
Now simplify:

$\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2}}{\log{\left(2 \right)}^{3} \tan{\left(x \right)}}$

The answer is:

$\frac{6 \log{\left(\sin^{2}{\left(x \right)} \right)}^{2}}{\log{\left(2 \right)}^{3} \tan{\left(x \right)}}$
