A) \[|A{{|}^{m-1}}\]
B) \[|A{{|}^{m}}\]
C) \[|A{{|}^{m+1}}\]
D) Zero
Correct Answer: C
Solution :
[c] Let \[A={{[{{a}_{ij}}]}_{m\times m}}\] be a matrix and \[C={{[{{c}_{ij}}]}_{m\times m}}\] be another matrix where \[{{c}_{ij}}\] is the cofactor of \[{{a}_{ij}}\] \[\therefore \] The value of \[\left| AC \right|={{\left| A \right|}^{m+1}}\]You need to login to perform this action.
