1. The problem is to determine if the expression is an indeterminate form. 2. Indeterminate forms occur in limits when substitution leads to expressions like $\frac{0}{0}$, $\frac{\infty}{\infty}$, $0 \times \infty$, $\infty - \infty$, $0^0$, $1^\infty$, or $\infty^0$. 3. To check if an expression is an indeterminate form, substitute the limit value and see if it matches any of these forms. 4. If you provide the specific expression or limit, I can help analyze it step-by-step.
