To simplify the expression \(3^2 \cdot 3^3\) using the Product Rule of Exponents, we can use the rule that states:
\[ a^m \cdot a^n = a^{m+n} \]
In this case, we have:
- \(a = 3\)
- \(m = 2\)
- \(n = 3\)
Applying the Product Rule:
\[ 3^2 \cdot 3^3 = 3^{2+3} = 3^5 \]
Now, we can express \(3^5\) as:
\[ 3^5 = 243 \]
So, the simplified expression is:
\[ 3^5 \text{ or } 243 \]
