Question

Consider the following statements:
$1$. Determinant is a square matrix.
$2$. Determinant is a number associated with a square matrix.
Which of the above statements is/are correct?

• A. $1$ only
• B. $2$ only
• C. Both $1$ and $2$
• D. Neither $1$ nor $2$

Answer 1

The correct option is A $1$ only

Example :

A =

$det$ A = = $ad-bc.$

From the above one it is verified that Determinant is a square matrix but It is not associated with absolute value at all except that they both use vertical lines.

Hence the statements $1$ only correct.
