Question

11.If A={a,b,c} andB={3,5} find A×B and B×A by using arrow diagram and prove that A×B is
not equal to B×A.
'best of luck'

Answer 1

Answer:

given

A= {a, b, c} and B = {3, 5}

A×B = {(a, 3), (a, 5), (b, 3), (b, 5), (c, 3), (c, 5) }

B×A = {(3,a),(3,b),(3,c),(5,a),(5,b),(5,c) }

here it is clear that the domain and range of both the expressions are different.. so both these expression are not equal
