Detail solution
  1. Let u=2x+1u = 2 x + 1.

  2. Apply the power rule: u5u^{5} goes to 5u45 u^{4}

  3. Then, apply the chain rule. Multiply by ddx(2x+1)\frac{d}{d x} \left(2 x + 1\right):

    1. Differentiate 2x+12 x + 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: xx goes to 11

        So, the result is: 22

      2. The derivative of the constant 11 is zero.

      The result is: 22

    The result of the chain rule is:

    10(2x+1)410 \left(2 x + 1\right)^{4}

  4. Now simplify:

    10(2x+1)410 \left(2 x + 1\right)^{4}


The answer is:

10(2x+1)410 \left(2 x + 1\right)^{4}
