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=

If A=[[2,3],[1,-2]] and A^-1=kA ,then the value of 'k' is

If A=[[1,2,3],[3,-2,1],[4,2,1]] and A^(3)=40I+KA then the value of 'K' is

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

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

Find k,if A=[[3,-2],[4,-2]] and A^2=kA-2I

If [[3,2],[2,-3]]=A is such that kA^(-1)=A then K is :
