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

The number in a power that is used as a factor is called the base.

To find the base in a power, you can look for the number that is being multiplied repeatedly. In the expression "a^n", the base is "a". For example, in the expression "2^5", the base is 2.
