A determinant of order three is worked out by expressing it in terms:
AOf empty ones
BOf smaller ones
COf larger ones
DOf equal ones
Answer & Solution
Correct answer: B. Of smaller ones
1. A three by three determinant is not read off directly.
2. It is expanded along a row or a column.
3. That expresses it in terms of smaller determinants.
