Do you know of any relationships between the concentration of H+ and OH- in aqueous solutions?

I understand that. But I still don't know how to answer my question. This question was in a previous exam paper, and the mark scheme states that the answer is 8, but I don't know how to work it out.

If anyone knows how could they please explain.

OK, what does [H+][OH-] equal (at a set temperature), according to the link above?

I just worked it out. Thanks for the help.

I was thinking of it in the back of my head, and then I got it :D.
