A) \[\left| adj\,A \right|=\left| A \right|\]
B) \[\left| adj\,A \right|={{\left| A \right|}^{2}}\]
C) \[\left| adj\,A \right|={{\left| A \right|}^{3}}\]
D) \[{{\left| adj\,A \right|}^{2}}=\left| A \right|\]
Correct Answer: B
Solution :
[b] \[\left| adj \right.A{{\left| = \right|}^{n-1}}\] {n is order od square matrix} If A is square matrix of order 3, then \[\left| adj \right.A\left| = \right|{{\left. A \right|}^{2}}\]You need to login to perform this action.
