To help you calculate the limit, please provide the specific limit expression you're working on.

For example, a limit can be written as: $\lim_{{x \to a}} f(x)$ or $\lim_{{x \to \infty}} f(x)$

If you upload an image or type the expression, I can assist you further!

Here are 5 related limit questions for practice:

1. Calculate $\lim_{{x \to 0}} \frac{\sin x}{x}$.
2. Calculate $\lim_{{x \to \infty}} \frac{1}{x^2}$.
3. Calculate $\lim_{{x \to \infty}} \frac{e^x}{x^2}$.
4. Calculate $\lim_{{x \to 2}} \frac{x^2 - 4}{x - 2}$.
5. Calculate $\lim_{{h \to 0}} \frac{(3+h)^2 - 9}{h}$.

Tip: If the direct substitution in the limit leads to an indeterminate form (like $0/0$), try techniques such as factoring, L'Hopital's Rule, or simplifying the expression.
