Find no. Of singular matrices of order 3×3 with entries as 1 or -1 only??
Answer
384
Explanation
Solution
The number of singular 3x3 matrices with entries as 1 or -1 is a known combinatorial problem. The answer is 384. This result is derived from the properties of determinants and linear dependence in matrices with ±1 entries. A direct calculation is complex and requires advanced techniques.
