Thank you for the opportunity to help you with your question!

For a is a real number and  n is a positive integer,   the expression  a^n  is a power expression of a.

where  a^n is equal to the product of a to itself, n number of times.

So the real number a multiplies itself  n number of times.

If we wrote the expression as a function :  f(n) = a^n  we a have a POWER FUNCTION

Please let me know if you need any clarification. I'm always happy to answer your questions.
