sqrt(log(x + sqrt(x) + (sqrt(x))^2 + sin(2*x)))

Detail solution

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

$\frac{2 \cos{\left(2 x \right)} + 2 + \frac{1}{2 \sqrt{x}}}{2 \left(\left(\left(\sqrt{x}\right)^{2} + \left(\sqrt{x} + x\right)\right) + \sin{\left(2 x \right)}\right) \sqrt{\log{\left(\left(\left(\sqrt{x}\right)^{2} + \left(\sqrt{x} + x\right)\right) + \sin{\left(2 x \right)} \right)}}}$
Now simplify:

$\frac{8 \sqrt{x} \cos^{2}{\left(x \right)} + 1}{4 \sqrt{x} \left(\sqrt{x} + 2 x + \sin{\left(2 x \right)}\right) \sqrt{\log{\left(\sqrt{x} + 2 x + \sin{\left(2 x \right)} \right)}}}$

The answer is:

\frac{8 \sqrt{x} \cos^{2}{\left(x \right)} + 1}{4 \sqrt{x} \left(\sqrt{x} + 2 x + \sin{\left(2 x \right)}\right) \sqrt{\log{\left(\sqrt{x} + 2 x + \sin{\left(2 x \right)} \right)}}}
