Question

contruct a matrix of order 2×2,whose element are given by aij=i+j.

Answer 1

a11=2, a12=3, a21=3, a22=4

so the matrix will be=2 3

3 4

Answer 2

Hi ,

aij = I + j -----( 1 )

a11 = 1 + 1 = 2

a12 = 1 + 2 = 3

a21 = 2 + 1 = 3

a 22 = 2 + 2 = 4

Therefore ,

Required matrix = 1 3
3 4

Put the bracket here .

I hope this helps you.
