[2],[0],[0],[8],[8]

if A is a square matrix such that Aadj(A)=[[8,0,0],[0,8,0],[0,0,8]] then (|adj(adjA)|)/(|adjA|) is

.Find x ,if the following matrix is a skew symmetric matrix [[0,4,-2],[-4,0,8],[2,-8,x]]

If A=[[-3,1,2],[0,0,1],[-3,5,0]] ,then 8|A|

if for any 2*2 square matrix A , A(adjA)=[[8 , 0] , [0 , 8]] then write the value of det.A

Given the matrix A=[(x,3,2),(1,y,4),(2,2z)]. If xyz=60 and 8x+4y+3z=20, then A(adjA) is equal to (a) [(6,4,0,0),(0,6,4,0),(0,0,6,4)] (b) [(8,8,0,0),(0,8,8,0),(0,0,8,8)] (c) [(6,8,0,0),(0,6,8,0),(0,0,6,8)] (d) [(3,4,0,0),(0,3,4,0),(0,0,3,4)]

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

Plot the points A(2,0), B(8,0),C(8,4) . Complete the rectangle ABCD and find the co-ordinates of point D.

Plot the points A(2,0), B(8,0),C(8,0),D(8,4) . Complete the rectangle ABCD and find the co-ordinates of point D.
