Integral(sqrt(x + 4), (x, 0, 1))
Detail solution

  1. Let u=x+4u = x + 4.

    Then let du=dxdu = dx and substitute dudu:

    ∫u du\int \sqrt{u}\, du

    1. The integral of unu^{n} is un+1n+1\frac{u^{n + 1}}{n + 1} when n≠−1n \neq -1:

      ∫u du=2u323\int \sqrt{u}\, du = \frac{2 u^{\frac{3}{2}}}{3}

    Now substitute uu back in:

    2(x+4)323\frac{2 \left(x + 4\right)^{\frac{3}{2}}}{3}

  2. Now simplify:

    2(x+4)323\frac{2 \left(x + 4\right)^{\frac{3}{2}}}{3}

  3. Add the constant of integration:

    2(x+4)323+constant\frac{2 \left(x + 4\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}

The answer is:

2(x+4)323+constant\frac{2 \left(x + 4\right)^{\frac{3}{2}}}{3}+ \mathrm{constant}
