Choose the correct answer. Let A be a square matrix of order 3 × 3, then is equal to A. B. C. D.
Let’s consider a determinant,
A = | a b c d e f g h i | | k A | = | k a k b k c k d k e k f k g k h k i |
The value of | k A | ,
| k A | = | k a k b k c k d k e k f k g k h k i | | k A | = k ⋅ k ⋅ k | a b c d e f g h i | | k A | = k 3 | a b c d e f g h i | = k 3 | A |
Therefore, the correct option is (C).
