4x2−1\sqrt{4 x^{2} - 1} 
sqrt(4*x^2 - 1)
Detail solution

  1. Let u=4x2−1u = 4 x^{2} - 1.

  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(4x2−1)\frac{d}{d x} \left(4 x^{2} - 1\right):

    1. Differentiate 4x2−14 x^{2} - 1 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: x2x^{2} goes to 2x2 x

        So, the result is: 8x8 x

      2. The derivative of the constant −1-1 is zero.

      The result is: 8x8 x

    The result of the chain rule is:

    4x4x2−1\frac{4 x}{\sqrt{4 x^{2} - 1}}

  4. Now simplify:

    4x4x2−1\frac{4 x}{\sqrt{4 x^{2} - 1}}

The answer is:

4x4x2−1\frac{4 x}{\sqrt{4 x^{2} - 1}}
