Determinants
If A and B are square matrices of order 3 such that |A| = 2 and |B| = 3, then |AB| equals
Select the correct option:
Solution
6
- Determinant of Product: A fundamental property of determinants states that for any two square matrices A and B, ∣AB∣=∣A∣×∣B∣.
- Application:
- ∣AB∣=(2)×(3)=6.
- Result: The determinant of the product is 6. Note that this property holds regardless of the matrix size of order n.
