If `A = {1} and B= {{1},2} "then show that " A cancel(sub)B`.

if A=[{:(0),(1),(2):}]and B=[3" "2" "1], then show that : (AB)'=B'A'

if A=[{:(0),(1),(2):}]and B=[3" "2" "1], then show that : (AB)'=B'A'

Whether the following statement is true ? Justify your answer. If A cancel (sub) B and B cancel (sub) C,then A cancel (sub) C.

If A={1,3,5,B} and B={2,4}, then 4in A b.{4}sub A c.B sub A d.none of these

Consider the sets phi, A = {1, 3}, B = {1, 5, 9}, C = {1, 3, 5, 7, 9} . Insert the symbol sub "or" cancel(sub) between each of the following pair of sets. A …….B

Consider the sets phi, A = {1, 3}, B = {1, 5, 9}, C = {1, 3, 5, 7, 9} . Insert the symbol sub "or" cancel(sub) between each of the following pair of sets. B ……..C

If A = {1,2,3,4},B={2,3,4} and C={1,3} , then find the set X such that : (i) X subB and X sub C (ii) X sub B and X cancel(sub)C (iii) X subA, X subB and X sub C .
