Transform

Detail solution

Let $u = \log{\left(7 x^{3} - 3 x \right)}$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(7 x^{3} - 3 x \right)}$ :
1. Let $u = 7 x^{3} - 3 x$ .
2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(7 x^{3} - 3 x\right)$ :
  1. Differentiate $7 x^{3} - 3 x$ term by term:
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
      So, the result is: $21 x^{2}$
    2. The derivative of a constant times a function is the constant times the derivative of the function.
      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: $3$
      So, the result is: $-3$
    The result is: $21 x^{2} - 3$
  The result of the chain rule is:
  
  $\frac{21 x^{2} - 3}{7 x^{3} - 3 x}$
The result of the chain rule is:

$\frac{21 x^{2} - 3}{2 \cdot \left(7 x^{3} - 3 x\right) \sqrt{\log{\left(7 x^{3} - 3 x \right)}}}$
Now simplify:

$\frac{3 \cdot \left(7 x^{2} - 1\right)}{2 x \left(7 x^{2} - 3\right) \sqrt{\log{\left(x \left(7 x^{2} - 3\right) \right)}}}$

The answer is:

$\frac{3 \cdot \left(7 x^{2} - 1\right)}{2 x \left(7 x^{2} - 3\right) \sqrt{\log{\left(x \left(7 x^{2} - 3\right) \right)}}}$
