Is 1*10^-7 the same as 10^-7? I'm pretty sure it is not...?

Okay, I know they are not the same. The reason I ask is because I often see textbooks saying the Kw for water is 10^-14, and Ka would be 10^-7 and Kb would be 10^-7. Isn't this incorrect? Shouldn't each of the respective values above be 1*10^-14, 1*10^-7, 1*10^-7?

    officially it should be 1.0 * 10^-7

    but 10^-7 is implcit the 1 in front

    thus, they are the same

    No, 1 times any number equals that number. 1*10^-7 is the same as 10^-7. Check it on a graphing calculator if you still aren't sure.

    They are two ways to write the same thing.
