If A = `[(3,1),(4,-1)]`, then find `A^(-1)`.

If A=[{:(1,3),(4,1):}] , then find |3A'| .

If A = [(2,-1,3),(1,3,2),(3,-4,-1)] , find A^-1 , Using A^-1 , solve the following system of linear equations 2x - y + 3z = 13, x + 3y + 2z = 1, 3x - 4y - z = 8 .

If A =[{:(1,-2,3),(0,-1,4),(-2,2,1):}] , then find (A)^(-1) .

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

If A=[(2,-3,5),(3,2,-4),(1,1,-2)] find A^(-1) . Use it to solve the system of equations 2x-3y+5z=11 , 3x+2y-4z=-5 and x+y-2z=-3

If A=[[1,-2,3],[0,-1,4],[-2,2,1]] , then find (A')^(-1)
