`\bf T= \begin{bmatrix} 4&2\\5&0\\\underset{row~3,col~1}{11}&-1\\8&3 \end{bmatrix}\impliedby \textit{11 is at 3,1}`

Answer 2

`a_(13)`

Explanation:

The address of an element is the row and column number of the element in the matrix.

If the matrix is
`\left[\begin{array}{ccc}4&2\\5&0\\11&-1\\8&3\end{array}\right]`

Then element 11 is row 3 and column 1. Its address is the column followed by the row. 11 is
`a_(13)`.
