Answer (1)
Identify the element in the 4th row and 4th column of the given matrix.
The element a 44 is located at the 4th row and 4th column.
The value of the element a 44 is 7.
Therefore, the final answer is 7 .
Explanation
Understanding the Problem We are given a 4x4 matrix and asked to find the value of the element in the 4th row and 4th column, denoted as a 44 .
Identifying the Element The matrix is given as: ( 1 3 8 5 5 4 6 2 6 7 1 8 2 9 3 7 ) We need to identify the element in the 4th row and 4th column.
Finding the Value The element in the 4th row and 4th column is 7. Therefore, a 44 = 7 .
Examples
In spreadsheet software like Excel, you often work with tables of data. Finding a specific value in a table is similar to finding an element in a matrix. For example, if you have a table of sales data with rows representing different products and columns representing different months, finding the sales figure for a specific product in a specific month is the same as finding an element in a matrix. This task is fundamental in data analysis and reporting.
