Question

a*b =1*ab‍‌ find identity and inverse elements

Answer 1

Answer:

The identity element of given binary operation is 0.

Step-by-step explanation:

According to the definition of identity, e is the identity element if

a*e=a=e*a

The given binary operation is defined as

a*b=a+b-ab

Let e be the binary element, then

Subtract a from both the sides.

The value of a can not be equal 1 because the binary operation * defined on Q-( 1 ).
