The question is asking about the property of addition shown in the equation:

[ 3 + [8 + (2)] = 3 + [(2) + 8] ]

This equation represents the Associative Property of Addition, which states that the way numbers are grouped in parentheses does not affect their sum. In this case:

• Left-hand side: $8 + (2)$
• Right-hand side: $(2) + 8$

The grouping has changed, but the total remains the same. Therefore, the correct answer is:
