Question

$$(\begin{matrix}03\\ 1&3\end{matrix})$$

Calculate Determinant

$9$

Steps Using Diagonal Rule

Find the determinant of the matrix.

$$det(\left(\begin{matrix}3&0\\1&3\end{matrix}\right))$$

For the $2\times 2$ matrix $\left(\begin{matrix}a&b\\c&d\end{matrix}\right)$, the determinant is $ad-bc$.

$$3\times 3$$

Multiply $3$ times $3$.

$$9$$

Evaluate

$\left(\begin{matrix}3&0\\1&3\end{matrix}\right)$
