This problem was confusing me, so any help would appreciated. I guess the thing that is confusing me most is how to notate each submatrix.
Use row reduction to show that the determinant of the n by n matrix symbolically represented by
[A C
O B]
is |A||B|, where
A is an m by m submatrix,
B is an (n-m) by (n-m) submatrix
C is an m by (n-m) submatrix, and
O is an (n-m) by m zero submatrix.
The thing that is confusing me most about this proof is how to notate the submatrices A, B, C, and O.
