se A is a matrix such that `A^2 =A and (I + A)^6 =1+ KA`, then k is

Suppose A is a matrix such that A^2 =A and (I + A)^6 =I+ KA , then K is________.

If B=[[-2,-2],[-1,0]] and A is a matrix such that A^(-1)B=B^(-1) and KA^(-1)=2B^(-1)+ I where K is some scalar then value of k is

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

If A is a skew-symmetric matrix such that (A^(n))'=kA^(n), n in N , then the value of k is

If S=[S_(ij)] is a scalar matrix such that s_(ii)=kandA is a square matrix of the same order,then AS=SA=?A^(k)( b) k+A(c)kA (d) kS

If S=[S_(i j)] is a scalar matrix such that s_(i i)=ka n dA is a square matrix of the same order, then A S=S A=? A^k (b) k+A (c) k A (d) k S

If A is a nonsingular matrix of type n Adj(AdjA)=kA , then k=
