1.If `A=[5,6,7]` and `B=[7,8,9]`then `A uu B` is equal to a) `(5,6,7,8,9}` b) `{5,6,7}`c) `{7,8,9}`d) None of these

If A = {5, 7, 8} and B = {9, 11}, then

If A={1,2,3,4,5,6,7,8} and B={1,3,4,6,7,8,9} then

If A = {1,3,5,7,9,} and B = {0,3,5,6,8} then A cap B is

If A={2,4,5},B={7,8,9} then find n(AxxB) .

Let A=[(3, 2),( 7, 5)] and B=[(6, 7),( 8, 9)] . Find (A B)^(-1)

The correct fraction in the box (\ ) is (\ ) - 5/8 = 1/4 (a) 6/8 (b) 7/8 (c) 1/2 (d) None of these

If |[x,3, 6],[ 3, 6,x],[6,x,3]|=|[2,x,7],[x,7, 2],[ 7, 2,x]|=|[4, 5,x],[5,x,4],[x,4, 5]|=0, then x is equal to a. 0 b. -9 c. 3 d. none of these

If the mean of and 7 is 7, then 6 (b) 7 8 (d) 9

Let A={1,2,3,5,9,7} and B={1,2,3,4,5,6,7,8,9,10} , show that A subset B

If A=|[3, 2], [7, 5]| and B=|[6 ,7], [8, 9]| , verify that (A B)^(-1)=B^(-1)A^(-1) .
