Question

How does the determinant value change when expansion is performed along a different row or column?

पर्याय

• The determinant value changes sign for every row expansion.

• The determinant value equals the selected cofactor.

• The determinant value is the same for any choice of row or column for expansion.

• The determinant value is zero for every column expansion.

Answer 1

A determinant may be expanded along any row or any column. The calculated determinant value remains the same in every such choice.
