algebra precalculus – How to read x^(n)-1 and x^(n-1)?

Now, it may sound absurd, but I would like to know (if exists), how to read $(x^{n-1})$ and $(x^n-1)$ distinctly and practice this it in everyday Mathematics.

As of now, I read $(x^{n-1})$ as, “x whole raised to power n-1” and $(x^n-1)$ as ” x raised to n whole minus 1″.

Similar confusing scenarios are also welcome.

Thank you.
