Question

• associative property of addition
• distributive property
• associative property of multiplication
• commutative property of addition

question help: post to forum

Explanation:

The given expression $(a \times b) \times c = a \times (b \times c)$ shows that the grouping of factors in multiplication does not change the product, which defines the associative property for multiplication. The other options do not match: associative addition applies to addition, distributive involves multiplication over addition, and commutative addition changes the order of addends.

Answer:

Associative Property of Multiplication
