State true of false. [[2,3,4],[5,6,7],[1,2,3]]=[[4,2,3],[7,5,6],[3,1,2]]

If =[[2,3,4],[1,2,3],[4,-5,7]], B= [[2,5,-1],[3,-1,2],[7,2,-3]] , verify that (A+B)'=A'+B'

If A=[[2,3,4],[1,2,3],[4,-5,7]], B= [[2,5,-1],[3,-1,2],[7,2,-3]] , verify that (A+B)'=A'+B'

If A=[[2,4,6],[3,5,7] ,show that (A')'=A

If A = {:[(4,2,3),(1,5,7)] and B = [(1,3,7),(0,4,1)] , find 2A + B.

Express the matrix A={:[(4,2,-1),(3,5,7),(1,-2,1)]:} as the sum of a symmetric matrix and a skew-symmetric matrix.

Express the matrix A=[[4, 2,-1], [3 ,5, 7], [1,-2 ,1]] as the sum of a symmetric and a skew-symmetric matrix.

Express the matrix A = [{:(4, 2,-1),(3,5,7),(1,-2,1):} ] as the sum of a symmetric and a skew-symmetric matrix.
