If `A= diagonal(3,3,3)` and `A^(4)=kA` then `k=`

Assertion (A) : If A=[{:(2,3),(5,-2):}] and A^(-1)=kA , then k=(1)/(9) Reason (R ) : |A^(-1)|=(1)/(|A|)

If A={:[(0,5),(4,0)]:}" and "A^(-1)=kA," then: "k=

In a parallelogram,the ends of one diagonal are (3,-4) and (2,3) .If the second diagonal has one end at (6,-1) then its other end is

If A=[[1,3] , [3,4]] and A^2-kA-5I_2=0 then k=

if A=[[1,22,3]] and A^(2)-kA-I_(2)=0 then the value of k is

If A is square matrix of order 3,|A|=1000 and |kA^(-1)|=27, then k is

The number of all 3times3 matrices A ,with entries from the set {-1,0,1} such that the sum of the diagonal elements of A A^(T) is 3 ,is k then (k)/(10) is

The number of all 3times3 matrices A ,with entries from the set {-1,0,1} such that the sum of the diagonal elements of A A^(T) is 3 ,is k then (k)/(10) is

If the extremities of the diagonal of a square are (1, -2, 3) and (3, -4, 3), the the length of the side is
