Question

How to write n*n*n*n*n*n*n as an exponential expression? Then evaluate.

Answer 1

Do you know what an exponent is?
Let's say you have n*n, you can rewrite that as n^2, which means n times itself 2 times.
Let's say you have n*n*n, you can rewrite it as n^3, which means n times itself 3 times (n*n*n)

Hope that helps with the problem.

Answer 2

Written in exponential notation that's    n⁷  .

That's all you can do with it if you don't know what number  'n'  is.
