If \(A\) is a square matrix of order 3 and \(|A|=4\), then the value of \(\left|2 A^T\right|\) is
- A 8
- B \(-8\)
- C \(-32\)
- D 32
Answer & Solution
Correct Answer
(D) 32
Step-by-step Solution
Detailed explanation
\(\left|2 A^T\right| = 2^3 \left|A^T\right|\) \(= 8 |A|\) \(= 8 \times 4\) \(= 32\)
