If `A = {1,2,3}, B = {2,3,4},` then `A - B = `

" If "A={1,2,3},B={2,3,4}" ,then "|(A times B)|nn(B times A)|=?

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

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

If A=[(1,2),(3,4)], B=[(2,1),(4,3)] , find (A-B)(A+B) and A^2-B^2 .

If A' = [[3,4],[-1,2],[0,1]] and B = [[-1,2,3],[1,2,3]] , then verify that (A - B)' = A' - B'

1) If A=[(1,2),(3,4)] , AdjA=[(4,a),(-3,b)] then the values of a and b are ..... a) a=-2, b=1 b) a=2, b=4 c)a=2, b=-1 d) a=1, b=-2

Solve for matrics A and B , where 2A + B = [{:( 3,-4),(2,7) :}] and A - 2B =[{:( 4,3),(1,1):}]

If A =[[1, 2, -3],[ 5, 0, 2],[ 1, -1, 1]], B=[[3, -1, 2],[ 4, 2, 5],[ 2, 0, 3]] and C=[[4 ,1 , 2],[ 0, 3, 2],[ 1, -2, 3]] then compute (A+B) and (B-C) . Also verify that A+(B-C)=(A+B)-C

If A' = [[3,4],[-1,2],[0,1]] and B = [[-1,2,3],[1,2,3]] , then verify that (A + B)' = A' + B'
