The correct Answer is:
To find the element in the second row and third column of the matrix \(\begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix}\), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Matrix**: The given matrix is: \[ \begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix} \] 2. **Locate the Rows and Columns**: - The first row consists of the elements \(1, 2, 3\). - The second row consists of the elements \(4, 5, 6\). - The third row consists of the elements \(7, 8, 9\). - The first column consists of the elements \(1, 4, 7\). - The second column consists of the elements \(2, 5, 8\). - The third column consists of the elements \(3, 6, 9\). 3. **Identify the Required Element**: - We need to find the element in the **second row** and **third column**. - From the second row \(4, 5, 6\), the third column element is \(6\). 4. **Conclusion**: Therefore, the element in the second row and third column of the matrix is \(6\). ### Final Answer: The element in the second row and third column of the matrix is **6**.
