The number of all possible matrices of order \(2 \times 3\) with entries −1 or 1 is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 64
A \(2 \times 3\) matrix has 6 entries, and each entry can be chosen in 2 ways (−1 or 1). By the multiplication principle,
\(\text{Number of matrices} = 2^6 = 64\)
