The problem is to evaluate the sum $3^3 + 3^3 + 3^3$.

1. Problem Description

The problem is to evaluate the sum $3^3 + 3^3 + 3^3$.

2. Solution Steps

We can rewrite the expression as a multiplication.

$3^3 + 3^3 + 3^3 = 3 \cdot 3^3$

Using the rule $a^m \cdot a^n = a^{m+n}$, we have:

$3 \cdot 3^3 = 3^1 \cdot 3^3 = 3^{1+3} = 3^4$

Now we can evaluate $3^4$:

$3^4 = 3 \cdot 3 \cdot 3 \cdot 3 = 9 \cdot 9 = 81$

3. Final Answer

81
