If A=[[0, 1, 2], [1, 2, 3], [3, a, 1]] and A^(-1)=(-1)/(2)[[-1, 1, -1], [8, -6, -2k], [-5, 3, -1]] , then

If A = [{:(0,1,2),(1,2,3),(3,1,1):}] and inverse of A is (1)/(2) [{:(1,-1,1),(-8,6, -2),(x, -3, 1):}] then x = _______________.

If A=[(1,2,3),(-1,0,2),(1,-8,-1)],B=[(4,5,6),(-1,0,1),(2,1,2)],C=[(-1,-2,1),(-1,2,3),(-1,-2,2)] , find (i) 2B-3C (ii) A-2B+3C .

If the matrix A =[(1,2,3,0),(2,4,3,2),(3,2,1,3),(6,8,7,a)] is of rank 3, then a=

If the matrix A=[(1,2,3,0),(2,4,3,2),(3,2,1,3),(6,8,7,alpha)] is of rank 3, then alpha=

sum-2,-2(1)/(2),-3(1)/(8),, to 6 terms.

If A = [[1,4],[2,8]] , B = [[3,2],[1,3]] then AB=

Find the rank of A=[[8,1,3,6],[0,3,2,2],[-8,-1,-3,4]]
