1. The user's question "With x^?" is unclear, but it suggests a query about expressions involving powers of $x$. 2. Let's explain how to interpret and work with expressions like $x^n$, where $n$ is any exponent. 3. The expression $x^n$ means $x$ multiplied by itself $n$ times if $n$ is a positive integer. 4. For example, $x^3 = x \times x \times x$. 5. If the exponent is zero, $x^0 = 1$ for any $x \neq 0$. 6. If the exponent is negative, $x^{-n} = \frac{1}{x^n}$. 7. Powers of $x$ are fundamental in algebra and help in constructing polynomials, solving equations, and modeling functions. 8. If you specify a particular expression, I can assist further!
