Important Questions from RD Sharma Solutions Class 12 Chapter 3 Exercise 3.1
Question :
Determine whether the operation ′O′ on Z defined by aOb=ab for all a,b∈Z is a binary operation or not :
Answer :
Given that ‘O’ is an operation that is valid in the Integers ‘Z’ and it is defined as given:
⇒aOb=abwhere,a,b∈Z
Since a∈z and b∈Z,
According to the problem it is given that on applying the operation ‘*’ for two given integers it gives Integers as a result of the operation,
⇒aOb∈Z……….(1)
Let us values of a = 2 and b = – 2 on substituting in the R.H.S side we get,
⇒ab=2−2
⇒ab=41
⇒ab∈/Z……….(2)
From (2), we can see that ab doesn’t give only Integers as a result. So, this cannot be stated as a binary function.
∴The operation ‘Ο’ does not define a binary function on Z.
