" If matrix "A=[[1,1,3],[1,3,-3],[-2,-4,-4]]" then find "A^(-1)

If A=[(2,-1),(3,4)] find |(A^(-1))^(-1)|

If A=[[1,-2,3],[0,-1,4],[-2,2,1]], then find |A| .

" (a) If "A=[[1,1,2],[2,1,3],[5,4,9]]" then find "|A|

If A=[[2,-3,5],[3,2,-4],[1,1,-2]], find A^(-1). Using A^(-1) solve the following system of equations: 2x-3y+5z=16;3x+2y-4z=-4;x+y-2z=-3
