The number in a power that is used as a factor is what?

In my math textbook it says it is a base.
Base When a number is raised to a power, the number that is used as a factor is the base. 
I'm doing a crossword and I need a word or words that equal 14. Does Factoredbase seem correct? That is the only thing I can come up with.

I mean 12 letters not 14. Sorry
