$$\sqrt[4]{\frac{2 x + 3}{x - 1}}$$

((2*x + 3)/(x - 1))^(1/4)

Detail solution

Let $u = \frac{2 x + 3}{x - 1}$ .
Apply the power rule: $\sqrt[4]{u}$ goes to $\frac{1}{4 u^{\frac{3}{4}}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{2 x + 3}{x - 1}$ :
1. Apply the quotient rule, which is:
  
  $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
  
  $f{\left(x \right)} = 2 x + 3$ and $g{\left(x \right)} = x - 1$ .
  
  To find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Differentiate $2 x + 3$ term by term:
    1. The derivative of the constant $3$ is zero.
    2. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $2$
    The result is: $2$
  To find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Differentiate $x - 1$ term by term:
    1. The derivative of the constant $-1$ is zero.
    2. Apply the power rule: $x$ goes to $1$
    The result is: $1$
  Now plug in to the quotient rule:
  
  $- \frac{5}{\left(x - 1\right)^{2}}$
The result of the chain rule is:

$- \frac{5}{4 \left(\frac{2 x + 3}{x - 1}\right)^{\frac{3}{4}} \left(x - 1\right)^{2}}$
Now simplify:

$- \frac{5}{4 \left(\frac{2 x + 3}{x - 1}\right)^{\frac{3}{4}} \left(x - 1\right)^{2}}$

The answer is:

$- \frac{5}{4 \left(\frac{2 x + 3}{x - 1}\right)^{\frac{3}{4}} \left(x - 1\right)^{2}}$
