The symmetric difference of `A={1,2,3}a n d\ B={3,4,5}` is a.`{1,2}` b. `{1,2,4,5}` c. `{4,3}` d. `{2,5,1,4,3}`

If A={1,2,3,4,5}a n d\ B={1,3,9, 12} then AnnB={1,3}dot

If A={1,2,3},\ B={3,4}a n d\ C={1,3,5} , find Axx(BnnC)

If A={1,2,3},\ B={3,4}a n d\ C={1,3,5} , find (AxxB)nn(AxxC)

If A={1,3,5, B}a n d\ B={2,4} , then 4 in A b. {4}subA c. BsubA d. none of these

If A={1,2,3},\ B={1,2,3,4},\ C={4,5,6},\ f i n d \ : Axx(B∩C)

If A={1,2,3,4,5,6,7,8}\ a n d\ B={1,3,5,6,7,8,9},\ t h e n\ A-B={2,4},\ B-A={9}dot

If A={1,2,3},\ B={1,2,3,4},\ C={4,5,6},\ fin d\ :(AxxB)nn(AxxC)

If A=[(2, 0,-3),( 4, 3, 1),(-5, 7, 2)] is expressed as the sum of a symmetric and skew-symmetric matrix, then the symmetric matrix is (a) [(2, 2,-4 ),(2, 3, 4),(-4, 4, 2)] (b) [(2, 4,-5),( 0, 3, 7),(-3, 1, 2)] (c) [(4, 4,-8),( 4, 6, 8),(-8, 8, 4)] (d) [(1, 0 ,0 ),(0 ,1 ,0),( 0, 0, 1)]

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

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