Question

If $\left[a_{ij}\right]$ is an element of matrix A then it lies in $i^{th}$ row and $j^{th}$ column of the matrix.

• A. True
• B. False

Answer 1

The correct option is A

True

$a_{ij}$ a general element of the matrix. Now where does it lie in the matrix? To specify its location we need to know its row number and column number. For $a_{ij}$ as per the convention the row and column numbers are given by i and j i.e., i is the row number and j is the column number. So we can say that $a_{ij}$ is an element which lies in the $i^{th}$ row and $j^{th}$ column.
