x36\sqrt{x - 36}
Detail solution
  1. Let u=x36u = x - 36.

  2. Apply the power rule: u\sqrt{u} goes to 12u\frac{1}{2 \sqrt{u}}

  3. Then, apply the chain rule. Multiply by ddx(x36)\frac{d}{d x} \left(x - 36\right):

    1. Differentiate x36x - 36 term by term:

      1. Apply the power rule: xx goes to 11

      2. The derivative of the constant 36-36 is zero.

      The result is: 11

    The result of the chain rule is:

    12x36\frac{1}{2 \sqrt{x - 36}}

  4. Now simplify:

    12x36\frac{1}{2 \sqrt{x - 36}}


The answer is:

12x36\frac{1}{2 \sqrt{x - 36}}
