If `A=[[4,3],[2,5]]` then `A^(2)` is

If A={:((4,3),(-5,2)):} , then A^(2)-6A =

If A=[(3,4,3),(2,5,7),(1,2,3)] then |Adj(Adj A)|=

If A=[[2,-1,-3],[3,-4,-2],[5,2,4]] then cofactor of element a_(32) is

If 2A+3B=[(2,-1,4),(3,2,5)] and A+2B=[(5,0,3),(1,6,2)] , then B is

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

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

If A=[(1,4),(3,2),(2,5)], B=[(-1,-2),(0,5),(3,1)] , find the matrix D such that A+B-D=0 .

If A=[[0,1,21,2,33,a,1]]A^(-1)=[[(1)/(2),(-1)/(2),(1)/(2)-4,3,c(5)/(2),(-3)/(2),(1)/(2)]]
