On set A={1,2,3}, relations R and S are given by R={(1,1),(2,2),(3,3),(1,2),(2,1)}, S={(1,1),(2,2),(3,3),(1,3),(3,1)}. Then

On set A={1,2,3}, relation R and S are given by R={(1,1),(2,2),(3,3),(1,2),(2,1)} and S={(1,1),(2,2),(3,3),(1,3),(3,1) Then

If Delta=|(1,2,3),(3,1,2),(2,3,1)| then |(3,1,2),(1,2,3),(2,3,1)| is

Let A = (1,2,3) and R = (1,1), (2,2), (1,2), (2,1), (1,3) then R is

If A=[(1,-2,1),(2,1,3)] and B=[(2,1),(3,2),(1,1)] then (AB)' is equal to
