    Indefinite Integral -Wolfram Alpha says I'm right but school software says otherwise!

    My work is attached. And here is the work shown by Wolfram Alpha: integral 2/(xln(8x - Wolfram|Alpha))

    I also attached a screen shot of what I am doing in terms of inputting my answer to the computer system. The letter C is not defined and I tried constants such as 5 and 0. I also tried not entering a constant.

    Am I making a stupid mistake?

    Try replacing the 5 with C. Or drop it altogether.

    I did both before your post and C is not in the context of the software and dropping it says my answer isn't correct.

    Maple gives a different form: 2\ln(\ln(8)+\ln(x)).
    Try that form.

    That form is also apparently wrong.

    In that case, the answer built intothe software is itself wrong.
