Construct a `2xx2` matrix `A=[a_(i j)]` whose elements `a_(i j)` are given by: (i) `a_(i j)=i+j` (ii) `a_(i j)=((i+j)^2)/2`

Explanation

To construct a \(2 \times 2\) matrix \(A = [a_{ij}]\) based on the given conditions, we will follow these steps for both cases.

### Case (i): \(a_{ij} = i + j\)

1. **Define the matrix structure**:
Since we need a \(2 \times 2\) matrix, we will have:
\[
A = \begin{bmatrix}
...
