Question

Let $A$ be a square matrix. If the value of $det\left(A\right)$ is $3$, then the value of $det\left(A^T\right)$ is equal to

• A. $3$
• B. $0$
• C. can't be determined
• D. $4$

Answer 1

The correct option is A $3$

We know that the determinant of the transpose of a square matrix is equal to the determinant of the matrix.
$\therefore |A|=|A^T|=3$
