$$$\left[\begin{array}{cc}1 & 8\\-2 & 17\end{array}\right]$$$'nin determinantı

Hesaplayın $$$\left|\begin{array}{cc}1 & 8\\-2 & 17\end{array}\right|$$$.

2x2 boyutlu bir matrisin determinantı $$$\left|\begin{array}{cc}a & b\\c & d\end{array}\right| = a d - b c$$$ olarak verilir.

$$$\left|\begin{array}{cc}1 & 8\\-2 & 17\end{array}\right| = \left(1\right)\cdot \left(17\right) - \left(8\right)\cdot \left(-2\right) = 33$$$

$$$\left|\begin{array}{cc}1 & 8\\-2 & 17\end{array}\right| = 33$$$A
