WebSep 16, 2013 · Proof. To verify the first sentence, swap the two equal rows. The sign of the determinant changes, but the matrix is unchanged and so its determinant is unchanged. Thus the determinant is zero. For the second sentence, we multiply a zero row by −1 and apply property (3). WebDeterminants - Axioms.
