Question

If $A$ is a matrix of order $3\times 3,$ then the number of minors in determinant of $A$ are

• A. 9
• B. 9.00
• C. 9.0

Answer 1

Answer: (A), (B), (C)

If $A$ is a matrix of order $3\times 3$ then number of minors in determinant of $A$ are $9.$
Since in a $3\times 3$ matrix, there are $9$ elements and each element corresponds to one minor.
