A=[[1,2],[3,4]]" and "A(adjA)=KI," then the value of "'K'is

If A=[[1,2],[2,1]] and A(adjA)=k , then the value of k is

Select the correct option from the given alternatives. If A=[[2,-4],[3,1]] and A(adj A)=KI then the value of k is….. i] 1 ii] -1 iii] 0 iv] 14

2) If A=[(1,2),(2,1)] and A(AdjA)=K.I then the value of K is

A = {:[(1,2),(3,4)]:} and A (adj A) = kI , then the value of 'k' is

If A=[[1, 2], [3, 4]] , then A(adjA)=kI, then k=

If A= [[1,2],[3,4]] , adjA= [[4,a],[-3,b]] , then the values of a and b are: (a) a=-2, b=1 (b) a=2, b= 4 (c) a=2, b=-1 (d) a=1, b=-2

If A=[[2,-2],[4,3]] then adjA

1) If A=[(1,2),(3,4)] , AdjA=[(4,a),(-3,b)] then the values of a and b are ..... a) a=-2, b=1 b) a=2, b=4 c)a=2, b=-1 d) a=1, b=-2

If M be a 3xx3 non-singular matrix with det(M)=alpha. If M^(-1)adj(adjA)=KI, then the value of K is

If A=[(cosx,sinx),(-sinx,cosx)] and A.(adjA)=k[(1,0),(0,1)] then the value of k is
