Question

find whether the operation * on q defined by a * b = a + ab is commutative or not ?​

Answer 1

Answer:

NOT COMMUTATIVE

Answer 2

Answer:

not commutative

Step-by-step explanation:

according to commutative property, if (a + b) = (b + a)

then only it is commutative

as per the question,

a*b= a+ ab; to be commutative (a*b) must be equal to (b*a)

b*a= b+ ba

but here (a*b) is not equal to (b*a)

therefore it is not commutative
