Final answer:
To derive the identity for a × (b × c) from the identity for (a × b) × c, use the associative property of multiplication.
Step-by-step explanation:
To derive the identity for a × (b × c) from the identity for (a × b) × c, we can use the associative property of multiplication.
Starting with (a × b) × c, we apply the associative property to the parentheses, which allows us to rearrange the order of multiplication:
(a × b) × c = a × (b × c)
This shows that a × (b × c) is equivalent to (a × b) × c. Thus, we have derived the identity for a × (b × c) from the original identity.
