construst a matrix of order 2`xx`2 whose elements are defined as `a_(ij)=i+3j.`

A

`A= [{:(-4" " 7),(-5" " 8):}].`

B

`A= [{:(4" " -7),(5" " -8):}].`

C

`A= [{:(4" " 7),(5" " 8):}].`

D

`A= [{:(4" " - 7),(5" " 8):}].`

Text Solution

Verified by Experts

The correct Answer is:
C
Let `A=[A_(ij)]_(2xx2)`
`=[{:(a_(11)" "a_(12)),(a_(21)" " a_(22)):}]`
Now , `a_(11) =1+3xx1=4`
`a_(11) =1+3xx2=7`
`a_(21)=2+3xx1=5`
`a_(22)=2+3xx2=8`
`therefore A= [{:(4" " 7),(5" " 8):}].`
