The determinants of the reverse identity matrics are defined as follow

$\left|I_{1}\right|=|1|=+1,\left|I_{2}\right|=\left|\begin{array}{ll}0 & 1 \\ 1 & 0\end{array}\right|=-\left|I_{3}\right|=\left|\begin{array}{lll}0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0\end{array}\right|$

If the points $(2,5),(4,6)$ and $(a,a)$ are collinear, then the value of $a$ is equal to

ব্যতিক্রমী ম্যাট্রিক্সের ক্ষেত্রে β = 3,-5 হলে, তা নিচের কোন ম্যাট্রিক্সের জন্য সত্য?

Three digits numbers $7x,36y$ and $12z$ where $x , y , z$ are integers from $0$ to $9 ,$ are divisible by a fixed constant $k.$ Then the determinant $\left| \begin{array} { l l l } { x } & { 3 } & { 1 } \\ { 7 } & { 6 } & { z } \\ { 1 } & { y } & { 2 } \end{array} \right|$ $\ +48$ must be divisible by

The determinants of the reverse identity matrices are defined as follow:

$\left|J_{1}\right|=|1|=+1,\left|J_{2}\right|=\left|\begin{array}{ll} 0 & 1 \\ 1 & 0 \end{array}\right|=-1,\left|J_{3}\right|=$$\left|\begin{array}{lll}0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0\end{array}\right|=-1, \cdots$ Find the determinant of $\mathrm{J}_{100}$.
