If `A= {2,4,6,9} and B= {4,6,18, 27, 54}, a in A, b in B`, find the set of ordered pairs such that 'a' is a factor of 'b' and `a lt b`

If a in {2,4,6,9}a n d b in {4,6, 18 , 27} , then from the set of al ordered pairs (a , b) such that a divides b a n d b

If A = {1,4,6,7} and B={4,7,9,10} , the find A oplus B .

If A={2,4,6,9},B={4,6,18,27,54} and a relation R from A to B is defined by R=(a,b):a in A ,b in B , a is a factor of b and a lt b} ,then find in roaster form .Also find its domain and range.

Express A={(a,b):2a+b=5,a,b in W} as the set ordered pairs.

If A={1,2,3,6},B={1,3,4,6} and C={3,4,5,6,8} , then find a)B-C b)C-A

Let A={1,2,3,4,5,6},B={2,4,6,8} Find A-B and B-A

Let A={1,2,3,4,5,6} and B = {2,4,6,8}. Find : A-B and B-A. Show that A-BneB-A .

Given that A = {2,4,6,7,8} and B = {1,2,3,4} Find A Delta B . The following are the steps involved in sovling the above problem. Arrange them in sequential order. (A) A Delta B = (A - B) uu (B - A) (B) A - B = {2,4,6.8} - {1,2,3,4} and B-A = {1,2,3,4} - {2,4,6,7,8} (C ) A Delta B = {6,7,8} uu {1,3} = {1,3,6,7,8} (D) A - B = {6,7,8} and B - A = {1,3}

If A=[{:(5,4),(2,3):}]" and "B=[{:(3,5,1),(6,8,4):}] , find AB and BA whichever exists.
