    Indefinite Integral



    Here is the answer:


    Here is what I've done so far:

    int (sqrt(2x) dx = int (2x^(1/2)
    ((1 / (1/2) +1)) (x ^((1/2)+1))

    = 2x^(3/2) / 3

    I'm not sure what to do after this. Any help would be appreciated. Thanks.

    Int(sqrt(2x))dx - Wolfram|Alpha

    You have to hit show steps in the corner to get how to do it. But Slovakiamaths solution is clearer .

    \int \sqrt{2x} dx= \sqrt{2}\int x^{1/2} dx

    Taking \sqrt{2x} out in front of the integral might simplify it for you.
