Question

a=[4 -7 3 -2] find the determinant

Answer 1

Answer:

13

Step-by-step explanation:

$\text{determinant of A} =\begin{vmatrix}4&-7\\ 3&-2\end{vmatrix}$

$\text{determinant of A} =\left( 4\times \left( -2\right) \right) -\left( 3\times \left( -7\right) \right)$

$\text{determinant of A} =-8+21=13$
