Let `A=[[2,1,3],[1,1,2],[3,1,1]]` and `A^(-1)=?`

Let A=[[3,1,4],[0,2,-1],[1,-3,5]] ,then 48*|A^(-1)|=---

Let A= [[3,1,4],[0,2,-1],[1,-3,5]] then 48*|A^(-1)| =---

Let A= [[1,0,2],[2,0,1],[1,1,2]] then det((A-I)^(3)-4A) is

Let A=[[1, 1,3], [5, 2,6],[-2,-1,-3]] . Find t r(A^(2012))

let A=[[1,0,5],[2,-1,3],[4,1,0]] and B=[[3,2,1],[0,2,1],[3,2,5]] find A',B' and (A+B)' show that (A+B)'=A'+B'

Let a matrix A=[[2,3],[1,2]] then A^(-1) will be

Let A =[(1,-1,1),(2,1,-3),(1,1,1)] and 10B=[(4,2,2),(-5,0,alpha),(1,-2,3)]. If B is the inverse of A, then alpha is :
