Construct a 2 × 2 matrix, where

aij=(i2j)22

Open in App
Solution

We know that the notation, namely A = [aij]m ×n, indicates that A is a matrix of order m × n. Also, 1 i m,1 j n;i,j ϵN.

(i) Here, A = [aij]2 ×2

A=(i2j)22,1i2:1j2,

a11=(12)22=12

a12=(12×2)22=92

a21=(22×1)22=0

a22=(22×2)22=2

Thus, A=[129202]2 ×2
