Question
For a 2×2 matrix A = [aij] whose elements are given by $\text{a}_{\text{ij}}=\frac{\text{i}}{\text{j}}$, write the value of a12.

Answer

Given that a 2×2 matrix A = [aij] whose elements are given by $\text{a}_{\text{ij}}=\frac{\text{i}}{\text{j}}.$
We need to find the value of a12.
Thus, $\text{a}_{12}=\frac{1}{2}.$
