If A = { 1 , 2 , 3 } , B = { 2 , 3 , 4 } , then A∩B =

If A = {1,2,3} and B={2,3,4} , then the symmetric difference of A and B is :

Let A={1,2,3,4,5}, B={1,2,3,4} and f:A rarr B is a function, then

If A = {1, 2, 3}, B = {3, 4, 5}, then (A nn B) xx A is

if A=[{:(1,2,-5),(-3,4,6):}]and B[{:(-2,3,-4),(1,2,3):}]' then find 2A+B.

if A=[{:(4,2),(-3,2),(1,3):}]and B=[{:(-1,3),(0,2),(2,-4):}], then find 3A-4B.

if A=[{:(3,-2),(7,1):}]and B=[{:(2,3),(-1,4):}], then find (i) A+B (ii) A-2B

If A={:[(1,2,3),(3,2,1)]:},B={:[(1,-1,4),(2,3,1)]:} , verify that (i) (B')'=B , (ii) (A-B)'=A'-B' (iii) (A+B)'=A'+B' , (iv) (kA)'=kA', where k is any constant (v) (2A+3B)'=2A'+3B'

If A={1,2,3} and B={2,3,4} , find which of the following are the functions from A to B? (i) f={(1,2),(2,3),(3,4)} (ii) g={(1,2),(1,3),(2,3),(3,4)} (iii) h={(1,3),(2,4)}

(i) if A=[{:(1,-4),(3,1):}]and b=[{:(1,0,5),(-2,4,3):}], then show that : (AB)'=B'A' (ii) if A=[{:(2,3),(0,1):}]and B=[{:(3,4),(2,1):}], then prove that : (AB)'=B'A'

If A=[[1,-2, 3,],[ 4, 2, 5,]] and B=[[2, 4], [2,3],[ 5, 1]] , then find AB, BA. Show that A B!=B A .
