Answer -
(A) 27┬а ┬а ┬а ┬а ┬а ┬а ┬а ┬а(B) 18
(C) 81┬а ┬а ┬а ┬а ┬а ┬а ┬а ┬а┬а(D) 512
Solution
Since, general matrix of order 3 x 3is┬а
This matrix has 9 elements.
The number of choices for┬а
┬аis 2 (as 0 or 1 can be used)
Similarly, the number of choices for each other element is 2.
Therefore, total possible arrangements(matrices) =┬а
times=┬а
Therefore, option (D) is correct.
