यदि `A xx B = {(1, 4), (2, 3), (3, 5), (4, 2), (2, 3), (4, 5)}` तो समुच्चय A होगा-

If A= {1, 2, 3}, B= {3, 4} and C= {4, 5, 6}, then (A xx B) uu (A xx C) = {(1, 3), (1,4), (1,5), (1,6), (2,3), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5),(3,6)}

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

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

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

If A=[(2 ,-3, -5), (-1, 4, 5),( 1, -3 ,-4)] and B=[(-1, 3, 5), (1,-3, -5) , (-1, 3, 5)] , show that A B=B A=O_3xx3 .

If A=[(2, -3, -5) , (-1, 4, 5), (1, -3, -4)] and B=[(2, -2, -4) , (-1, 3, 4),( 1, -2, -3) ] , show that A B=A and B A=B .
