If $A=\begin{bmatrix}-2 & 3\\k & 4\end{bmatrix}$ is a singular matrix then value of k is : |
$k=\frac{8}{3}$ $k=-\frac{8}{3}$ $k=-\frac{3}{8}$ $k=\frac{3}{8}$ |
$k=-\frac{8}{3}$ |
The correct answer is Option (2) → $k=-\frac{8}{3}$ $A=\begin{bmatrix}-2 & 3\\k & 4\end{bmatrix}$ A → singular $|A|=0$ $⇒-8-3k=0$ so $k=-\frac{8}{3}$ |
