Question

If A = (aij) is a 2 x 3 matrix and aij = i+j, write down the
matrix completely

Shalini · Answer

Let the matrix be A = [ a11 a12 a13 ] first row and [ a21 a22
a23 ] second row
Now, a11= 1+1= 2 ; a12= 1+2 =
3 ; a13= 1+3= 4 ;
a21= 2+1= 3; a22= 2+2 =
4 ; a23= 2+3 =
5
thus, A= [ 2 3 4 ] first row and [ 3 4 5 ] second
row

If A = (aij) is a 2 x 3 matrix and aij = i+j, write down the matrix completely.
