Answer
The commutative property was used twice to rearrange the factors and change the grouping of the expression.
Solution
We start with the expression
Our goal is to rewrite it as
Notice that the original expression groups
and
together, while the new expression groups
and
. We can achieve this change by rearranging the factors.
Step 1. Write the product without parentheses (since multiplication is associative):
Step 2. Use the commutative property of multiplication to swap the order of
and
:
Step 3. Regroup the factors (using associativity) so that
is separate:
In this process we have used the commutative property twice (to rearrange the order) in order to have the desired grouping. Therefore, the property used is:
- The commutative property used twice.

Extra Insights
To rewrite the expression
as
, we can leverage the commutative property, which states that the order of addition or multiplication does not affect the sum or product. By applying the commutative property to rearrange the terms, we can successfully achieve the desired expression.
Additionally, remember that the associative property can also play a role here, as it allows us to change the grouping of the numbers without altering the sum or product. Understanding both properties can help you manipulate expressions more freely!
