Explanation:
Exponents are also called indices. (singular is index)
They are the small numbers to the top right of a base.
An index tells us how many of the same base are multiplied together.
In algebra we don't use x signs between the factors.
We write the variables in alphabetical order, using indices to show how many of the same base there are.
