Question

Sarrus Rule says that determinant of the three colums on the left is the sum of products along dashed diagonals minus the sum of products along solid diagonals.

• A. True
• B. False

Answer 1

The correct option is A True

Sarrus Rule says that determinant of the three colums on the left is the sums of products along dashed diagonals minus the sum of products along solid diagonals
Determinant = $a_{11}{a}_{22}{a}_{33}+a_{12}{a}_{23}{a}_{31}+a_{13}{a}_{21}\left(a_{32}\right)-a_{31}{a}_{22}{a}_{13}-a_{32}{a}_{23}{a}_{11}-a_{33}{a}_{21}{a}_{12}$
