Sure, I'll adjust the expression $x^n$ to $(x-1)^n$. Could you clarify the context? For instance, are you working on expanding the binomial, solving an equation, or something else? Here's the adjusted expression:

$(x-1)^n$

If you need a specific operation or explanation regarding this, let me know. Below are some related explorations we can delve into:

1. Expand $(x-1)^n$ using the Binomial Theorem.
2. Differentiate $(x-1)^n$ with respect to $x$.
3. Integrate $(x-1)^n$ with respect to $x$.
4. Solve $(x-1)^n = 0$ for $x$ or $n$.
5. Analyze the behavior of $(x-1)^n$ for large $n$ or specific ranges of $x$.

Tip: When working with $(x-1)^n$, ensure you clearly understand how $x$ and $n$ influence the expression, especially in expansions or calculus applications.
