I need help with this question. It is not from an assignment. It is in my book, and it tries to explain how to do it, but I don't understand...

Determine the pH of a solution with a hydrogen concentration of 3.5 x 10^-4

This is what it says.

pH = -log [3.5 x 10^-4]
= -log 3.5 - log 10^-4
= - .54 - (-4)
= - .54 + 4
= 3.46

Where does the .54 come from?

And what Exactly does log mean in this?
