" If "A=[[4,0,0],[0,4,0],[0,0,4]]," then find the value of "|" adj "A|

if A =[[a,0,0],[0,a,0],[0,0,a]] , then the value of |A||adj A| is

If [[2x+y,3y],[0,4]]=[[6,0],[0,4]] then find the value of x.

If A=[[4,0,00,4,00,0,4]] then adj(A)=

If A=[[a,0,0] , [0,a,0] , [0,0,a]] then |adj A|=

Let A be a square matrix of order 3 whose elements are real numbers and adj.(adj(adj.A))=[[16,0,-3],[0,4,0],[0,3,4]] then find absolute value of Tr(A^(-1)) [Note: adj(P) and Tr(P) denote adjoint matrix and trace of matrix P respectively]

If A=[[1,2,3],[2,3,4],[0,0,2]] then the value of adj(adjA) is-

Let A be a square matrix of order 3 such that adj. (adj. (adj. A)) =[(16,0,-24),(0,4,0),(0,12,4)] . Then find the value of |A|
