If A = diag (4, 2, 1) then det A is equal to

If A= diag (1,4,5) then A^(-1) is equal to

If A is an invertible matrix of order 2, then det (A^(-1)) is equal to

if A is a square matrix such that A^(2)=A, then det (A) is equal to

If A is an invertible matrix of order 2 then det (A^(-1)) is equal to (a) det (A) (b) (1)/(det(A))(c)1 (d) 0

If A and B are non-singular matrices of Q. 1 order 3times3 such that A=(adj B) and B=(adj A) then det(A)+det(B) is equal to
