Simplify the Expression: 3² × 3³ Using Laws of Exponents

To solve this problem, we'll follow these steps:

• Step 1: Identify the base and exponents
• Step 2: Apply the exponent multiplication rule
• Step 3: Perform the calculations

Let's work through each step:
Step 1: We have $3^2$ and $3^3$. Both have the same base, which is 3.
Step 2: According to the exponent multiplication rule $a^m \times a^n = a^{m+n}$, we add the exponents:
$2 + 3 = 5$.
Step 3: Rewrite the expression as a single power:
$3^2 \times 3^3 = 3^{2+3} = 3^5$.

Therefore, the simplified expression is $\boldsymbol{3^5}$, which corresponds to choice 2.
