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

1. ## 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?

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

3. 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.

5. That form is also apparently wrong.

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