The commutative property of multiplication states that:
[tex]c\cdot d=d\cdot c,[/tex]for every c and d.
Now, if choose:
• c = 3a,
,• d = 10b.
Replacing c and d in the expression above, we have:
[tex](3a)\cdot(10b)=(10b)\cdot(3a)\text{.}[/tex]We conclude that (3a)(10b) = (10b)(3a) shows the conmmutative property of multiplication.
Answer
(3a)(10b) = (10b)(3a)
