Let X = { 1,2,3,4 } and R = { (1,1), (1,2),(1,3),(2,2), (3,3),(2,1),(3,1),(1,4),(4,1)}. Then R is

Let A = {1,2,3,4} and R be a relation in A given by R = {(1,1) (2,2) (3,3) (4,4) (1,2) (2,1) (3,1) (1,3)} . Then R is

The adjoint of the matrix [(2,5),(3,1)] is (A) [(2,5),(3,1)] (B) [(1,-5),(-3,2)] (C) [(1,-3),(-5,2)] (D) [(-1,3),(5,-2)]

The adjoint of the matrix [(2,5),(3,1)] is (A) [(2,5),(3,1)] (B) [(1,-5),(-3,2)] (C) [(1,-3),(-5,2)] (D) [(-1,3),(5,-2)]

I: If A=[(1,2),(3,4)] then A^(-1)=[(4,-2),(-3,1)] II: If A=[(3,4),(2,1)] then A^(-1)=1/5[(-1,4),(2,-3)]

If A{:[(1,2,3,5,6),(4,-1,2,-3,1)]:}andB={:[(5,3),(2,1),(-3,5),(4,1),(1,2)]:} , then find AB and BA.

If A=[(1,-1),(3,4),(-1,5)],B=[(-1,2),(3,1)] then AB=

Let A={1,2,3,4} and R be a relation in given by R= (1,1), (2, 2), (3. 3). (4,4), (1,2), (2,1),(3,1), (1,3)} . Then R is
