If A = [[1,0,1],[0,2,3],[1,2,1]] and B = [[1,2,3],[1,1,5],[2,4,7]] , then find a matrix X such that XA = B .

If A=[(0,1,2),(1,2,3),(3,1,1)] and A^(-1)=[(1//2,-1//2,1//2),(-4,3,x),(5//2,-3//2,1//2)] then

If A=[(0,1,2),(1,2,3),(3,a,1)] and A^(-1)=[(1//2,-1//2,1//2),(-4,3,c),(5//2,-3//2,1//2)] , then the values of a and c are equal to

Show that [[1,2,3],[0,1,0],[1,1,0]] [[-1,1,0],[0,-1,1],[2,3,4]] ne [[-1,1,0],[0,-1,1],[2,3,4]][[1,2,3],[0,1,0],[1,1,0]]

Show that: [[1,2,3],[0,1,0],[1,1,0]][[-1,1,0],[0,-1,1],[2,3,4]] ne [[-1,1,0],[0,-1,1],[2,3,4]][[1,2,3],[0,1,0],[1,1,0]]

If A=[(0,1,2),(1,2,3),(3,a,1)] and A^(-10)=[(1//2,1//2,1//2),(-4,3,c),(5//2,-3//2,1//2)] , then the values of a and c are equal to

If A = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8

find the rank of matrix A=[[2,-1,-2,-4],[1,3,-1,-1],[3,1,-1,-1],[6,3,0,-7]]

If A=[[7,-3,-3],[-1,1,0],[-1,0,1]] then A^(-1) is
