Final Answer
Step-by-step Solution
Specify the solving method
Evaluate the limit $\lim_{x\to\infty }\left(\frac{x^2}{e^x}\right)$ by replacing all occurrences of $x$ by $\infty $
Infinity to the power of any positive number is equal to infinity, so =\infty$
In the fraction $\frac{\infty }{e^{\infty }}$, as the expression of the denominator grows faster than the numerator, the quotient approaches $0$
