If `A=[[5,-4],[2,-1]]` then show that `|A|`=`|A^(T)|`

If A=[[2,4],[-5,-1]] show that: |3A|=9|A|

" 0.5"" If "A=[[4,5],[2,1]]" then,show that "A^(-1)=(1)/(6)(A-51)" ,where "1" is ldentity matrix "

If A=[[3m,-4],[1,-1]] , show that (A-A^T) is skew symmetric matrix, where A^T is the transpose of matrix A.

If A=[[ 1 ,4 , 7 ] , [2 , 5 , 8 ]] and B=[[-3, 4 , 0 ],[ 4 ,-2 , -1 ]] then show that ( A + B )^T = A^T + B^T

If A=[[3,4],[5,1]] , show that A-A^T is a skew symmetric matrix, where A^T denotes the transpose of matrix A

If A=[[2,4],[5,6]] , show that (A-A^T) is a skew symmetric matrix, where A^T is the transpose of matrix A.

If A= [[1,3],[2,-1]] and B= [[4,5],[0,6]] ,show that (A+B)^T=A^T+B^T

If A=[[4,1],[5,8]] , show that A+A^T is symmetric matrix, where A^T denotes the transpose of matrix A

If A=[[3,2,1] , [-5,0,-6]] and B= [[-4,-5,-2], [3,1,8]] then verify that (A+B)^T=A^T+B^T

If A=[[7,-2],[-1,2],[5,3]] and B=[[-2,-1],[4,2],[-1,0]] then find AB^(T) and BA^(T)
