Simplify $\left(9^x\right)^2$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $x$ and $n$ equals $2$

Applicare la formula: $\lim_{x\to c}\left(a^b\right)$$={\left(\lim_{x\to c}\left(a\right)\right)}^{\lim_{x\to c}\left(b\right)}$, dove $a=9$, $b=2x$ e $c=\infty $

Applicare la formula: $\lim_{x\to c}\left(a\right)$$=a$, dove $a=9$ e $c=\infty $

Applicare la formula: $n^{\infty }$$=\infty $, dove $n=9$
