What is the [OH-] in a solution that has a pH of 10.07? Use E notation and 3 significant figures.?

I'm stuck on my hw!! I know the pOH is is 3.93, and that if you take the log[OH] = 3.93

so am i missing a huge thing here? what's the reverse of log? do I raise 10 to the 3.93 power??

please help!

Answer:
raise 10 to the negative 3.93 =)

With three sigfigs I get 1.17E-4
