Question
Construct a $2 \times 3$ matrix $A=\left[a_{i j}\right]$ whose elements $a_{i j}$ are give by:
$a_{i j}=i . j$
✓

Answer

Here,
$a_{i j}=\mathrm{i} . \mathrm{j} .1 \leq \mathrm{i} \leq 2$ and $1 \leq \mathrm{j} \leq 3$
$a_{11}=1 \times 1=1, a_{12}=1 \times 2=2, a_{13}=1 \times 3=3$
$a_{21}=2 \times 1=2, a_{22}=2 \times 2=4$ and $a_{23}=2 \times 3=6$
