" If "A" .adj "A=[[8,0],[0,8]]" then determinant of "A" is..."

For any square matrix of order 2, if A (adj A) = [{:(8, 0),( 0,8):}], then the value of |A| is :

If A=[[0.8, 0.6] , [-0.6, 8.0]] then find A^3

If A=[[0.8,0.6-0.6,8.0]] then find A^(3)

For any 2×2 matrix, If A.(adj A)=[(8,0),(0,8)] then find |A|.

" A is a square matrix of order "3" where "A=([1,2,3],[2,3,4],[5,6,8])" then the value of "|(" adj "(adj(adj(adj A))))" is equal to "

If A=[[1,0,0],[0,5,0],[0,0,2]] then | adj "A|=

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