If `A =((4,22),(-1,-6))`, then find `A +A^-1.`

If A = [(2,2),(-2,1)] , Find A^(-1) .

if A=[[1,2,22,1,22,2,1]] then find the value of A^(2)-4A+5I_(3) then find the value of

Show that the matrix A=[[1,2,22,1,22,2,1]] hence find A^(-1)

If A=[{:(2,2),(-3,1),(4,0):}],B=[{:(6,2),(1,3),(0,4):}]andC=[{:(-8,-4),(2,-4),(-4,-4):}] , then find the additive inverse of matrix A.

If a + (1)/(a) = 6 , then find a^(4) + (1)/(a^(4)) .

If A = {:[(2,2),(-3,1),(4,0)], B = [(6,2),(1,3),(0,4)] , find the matrix C such that A+B+C is a zero matrix.

If [(x+1,-3,4),(-5,x+2,2),(4,1,x-6)]=0 then x=

If |(1,-3,4),(-5,x+2,2),(4,1,x-6)|=0 then x equals

If A=[(1,-1,3),(3,2,1),(4,5,6)] then cofactor of A_(22) is
