1.	If A be any matrix of order 2x2 and its entries are {-1, 0, 1}, then find the total no. of matrices possible, such that \|A\| = 0.
Answer» ong>ANSWER: a 2 × 2 matrix, the total number of elements present are 4. Each element can be replaced with either 1 or 0. Thus, there are two ways of filling each of the FOUR spaces. Thus the total number of such matrices will be 2×2×2×2 = 2⁴ matrices. Therefore, the number of possible matrix of 2×2 order with each entry as 0 or 1 is equal to 16.

Answer»

a 2 × 2 matrix, the total number of elements present are 4. Each element can be replaced with either 1 or 0. Thus, there are two ways of filling each of the FOUR spaces.

Thus the total number of such matrices will be 2×2×2×2 = 2⁴ matrices.

Therefore, the number of possible matrix of 2×2 order with each entry as 0 or 1 is equal to 16.
