How to read $x^n-1$ and $x^{n-1}$?

Question

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.

Answer 1

For $x^{n-1}$, $``x$ whole raised to $n-1"$ looks great.

For $x^n - 1$, I'd suggest $``1$ less than $x^n"$

Answer 2

To read aloud I would say, "x to the power, pause, n minus 1", and "x to the power n, pause, minus 1". The position of the pause is used to communicate the implied brackets. If this is not clear enough, then "x to the power open bracket n minus 1 close bracket".

Answer 3

For $x^{n-1}$: $x$ raised to the difference of $n$ and $1$. And for $x^n-1$: The difference of $x$, raised to $n$, and $1$.
