Construct a `2xx2` matrix, where
(i) `a_("ij")=((i-2j)^(2))/(2)` (ii) `a_("ij")=|-2i+3j|`

Explanation

To construct the required \(2 \times 2\) matrices based on the given formulas, we will follow these steps:

### Part (i): Constructing the matrix \(A\) where \(a_{ij} = \frac{(i - 2j)^2}{2}\)

1. **Calculate \(a_{11}\)**:
\[ a_{11} = \frac{(1 - 2 \cdot 1)^2}{2} = \frac{(1 - 2)^2}{2} = \frac{(-1)^2}{2} = \frac{1}{2} \]
