\/ 2*x - 3 
$$\sqrt{2 x - 3}$$
sqrt(2*x - 3)
Detail solution
  1. Let .

  2. Apply the power rule: goes to

  3. Then, apply the chain rule. Multiply by :

    1. Differentiate 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: goes to

        So, the result is:

      2. The derivative of the constant is zero.

      The result is:

    The result of the chain rule is:

  4. Now simplify:


The answer is:

  _________
\/ 2*x - 3 
$$\frac{1}{\sqrt{2 x - 3}}$$
The second derivative [src]
     -1      
-------------
          3/2
(-3 + 2*x)   
$$- \frac{1}{\left(2 x - 3\right)^{\frac{3}{2}}}$$
The third derivative [src]
      3      
-------------
          5/2
(-3 + 2*x)   
$$\frac{3}{\left(2 x - 3\right)^{\frac{5}{2}}}$$
