Question 1165665
The property being used for this question is the commutative property. The reason is because the numbers inside the parentheses are switched, but the numbers aren't replaced by the other number (like 1). Associative property is not being used in this problem nor the distributive property.

Associative replaces the number inside the parentheses by the number that was originally not in the parentheses. Ex. (61+65)+95 = 61+(65+95)

Distributive multiplies the number(s) inside the parentheses. Ex. 4(7+5)=28+20.

So the answer is commutative property.
