If matrix `A= [(1, 2, 3),( 2, 3, 1),( 3, 1, 2)]` then `|adjA|` is: (A) 18 (B) -18 (C) 324 (D) -324

If A=[[2, 0, -1], [3, 1, 2], [-1, 1, 2]] , then adjA=

If A=[[1, -1, 2], [-2, 3, 5], [-2, 0, -1]] , then adjA=

If A=[[1, -1, 2], [3, 0, -2], [1, 0, 3]] , then (adjA)A=

If A is any matrix of order 3x3 and |adjA| = 36, then |2A| is (A) ±6 (B) ±48 (C) ±36 (D) ±216

If matrix A=[{:(3,2,4),(1,2,-1),(0,1,1):}]and A^(-1)=1/k adj A, then k is

If A is a square matrix of order 3 and |A|=3 then |adjA| is (A) 3 ; (B) 9 ; (C) (1)/(3) ; (D) 0

If the matrix A= [(3, 2, 1),( 6x^(2), 2x^(3), x^(4)),( 1, a, a^(2))] then (d^(2))/(dx^(2))(|A(adjA)|^((1)/(3))) at x=a is

If |A|=3 and A^(-1)=[(3,-1),((-5)/3,2/3)] then adjA=?

3, 7, 6, 5, 9, 3, 12, 1, 15, (......) (a) 18 (b) 13 (c) -1 (d) 3

If A=[(0,2,-3),(-2,0,-1),(3,1,0)] then A is (A) diagonal matrix (B) symmetric matix (C) skew symmetric matrix (D) none of these
