We are asked to simplify the expression $9^8 \cdot 9^2$.

1. Problem Description

We are asked to simplify the expression $9^8 \cdot 9^2$.

2. Solution Steps

To solve this problem, we can use the property of exponents that states $a^m \cdot a^n = a^{m+n}$, where $a$ is the base and $m$ and $n$ are the exponents.

In this case, $a = 9$, $m = 8$, and $n = 2$.

Applying the formula, we have:

$9^8 \cdot 9^2 = 9^{8+2} = 9^{10}$

Therefore, $9^8 \cdot 9^2 = 9^{10}$.

3. Final Answer

$9^{10}$
