$$$\left[\begin{array}{cc}1 & 4\\0 & 5\end{array}\right]$$$'nin determinantı

Hesaplayın $$$\left|\begin{array}{cc}1 & 4\\0 & 5\end{array}\right|$$$.

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

$$$\left|\begin{array}{cc}1 & 4\\0 & 5\end{array}\right| = \left(1\right)\cdot \left(5\right) - \left(4\right)\cdot \left(0\right) = 5$$$

$$$\left|\begin{array}{cc}1 & 4\\0 & 5\end{array}\right| = 5$$$A
