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

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}

The symmetric difference of A={1,2,3} and B={3,4,5} is {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=[(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=[(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)]
