A and B are two matrices of same order `3 xx 3`, where `A=[{:(1,2,3),(2,3,4),(5,6,8):}],B=[{:(3,2,5),(2,3,8),(7,2,9):}]`
The value of |adj (AB)| is

A and B are two matrices of same order 3 xx 3 , where A=[{:(1,2,3),(2,3,4),(5,6,8):}],B=[{:(3,2,5),(2,3,8),(7,2,9):}] The value of adj (adj A) is,

A and B are two matrices of same order 3 xx 3 , where A=[{:(1,2,3),(2,3,4),(5,6,8):}],B=[{:(3,2,5),(2,3,8),(7,2,9):}] Value of |adj (adj adj( adj A)))| is

Let A and B are two matrices of same order i.e. where A=[(1,-3,2),(2,K,5),(4,2,1)], B=[(2,1,3),(4,2,4),(3,3,5)] If K = 2 then tr (AB) + tr (BA) is equal to

Let A and B are two matrices of same order i.e. where A=[(1,-3,2),(2,K,5),(4,2,1)], B=[(2,1,3),(4,2,4),(3,3,5)] If A is singular matrix then tr(A + B) is equal to

Let A and B are two matrices of same order i.e. where A=[(1,-3,2),(2,K,5),(4,2,1)], B=[(2,1,3),(4,2,4),(3,3,5)] If C = A – B and tr (C) = 0 then K is equal to-

If A=[(3,2),(7,5)], B=[(6,7),(8,9)] , then adj (AB) is equal to

Given A=[{:(2,4,0),(3,9,6):}] "and" B=[{:(1,4),(2,8),(1,3):}] , is (AB)=B'A'?

If A=[(3,9,0),(1,8,-2),(7,5,4)], B=[(4,0,2),(7,1,4),(2,2,6)] , verify that 3(A+B)=3A+3B .

Verify (AB)^(-1)=B^(-1)A^(-1) for the matrices A and B where A=[{:(3,7),(2,5):}] and B=[{:(6,8),(7,9):}]
