Detail solution

Let $u = \tan{\left(3 x^{2} \right)}$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \tan{\left(3 x^{2} \right)}$ :
1. Rewrite the function to be differentiated:
  
  $\tan{\left(3 x^{2} \right)} = \frac{\sin{\left(3 x^{2} \right)}}{\cos{\left(3 x^{2} \right)}}$
2. Apply the quotient rule, which is:
  
  $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
  
  $f{\left(x \right)} = \sin{\left(3 x^{2} \right)}$ and $g{\left(x \right)} = \cos{\left(3 x^{2} \right)}$ .
  
  To find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Let $u = 3 x^{2}$ .
  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 $\frac{d}{d x} 3 x^{2}$ :
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x^{2}$ goes to $2 x$
      So, the result is: $6 x$
    The result of the chain rule is:
    
    $6 x \cos{\left(3 x^{2} \right)}$
  To find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Let $u = 3 x^{2}$ .
  2. The derivative of cosine is negative sine:
    
    $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} 3 x^{2}$ :
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x^{2}$ goes to $2 x$
      So, the result is: $6 x$
    The result of the chain rule is:
    
    $- 6 x \sin{\left(3 x^{2} \right)}$
  Now plug in to the quotient rule:
  
  $\frac{6 x \sin^{2}{\left(3 x^{2} \right)} + 6 x \cos^{2}{\left(3 x^{2} \right)}}{\cos^{2}{\left(3 x^{2} \right)}}$
The result of the chain rule is:

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

$\frac{3 x}{\cos^{2}{\left(3 x^{2} \right)} \sqrt{\tan{\left(3 x^{2} \right)}}}$

The answer is:

$\frac{3 x}{\cos^{2}{\left(3 x^{2} \right)} \sqrt{\tan{\left(3 x^{2} \right)}}}$
