Answer:
a · b = b · a
Step-by-step explanation:
Commutative property of multiplication states that the order of multiplication in real numbers does not matter,
I.e.
m × n = n × m
∀ m, n ∈ R
Thus, the correct option that represents the commutative property of multiplication is,
a · b = b · a
Note :
a + b = b + a represents commutative property of addition,
a + 0 = a represents the additive identity property,
a . 1 = a represents the multiplicative identity property.
