![**Matrix Multiplication Exercise**
Use the matrices below. Perform the indicated operation.
Matrix \( A \) is a \( 3 \times 3 \) matrix:
\[
A = \begin{bmatrix} 8 & 3 & 4 \\ 1 & 6 & 5 \\ 1 & -9 & -6 \end{bmatrix}
\]
Matrix \( B \) is a \( 3 \times 3 \) matrix:
\[
B = \begin{bmatrix} -1 & 6 & 1 \\ -3 & 6 & 6 \\ -5 & 11 & -7 \end{bmatrix}
\]
**Task:**
Find the product \( AB \).
**Explanation:**
To find the product \( AB \), multiply each row of matrix \( A \) with each column of matrix \( B \). The result will be a \( 3 \times 3 \) matrix. The diagram (not shown here) includes arrows indicating the direction of row and column operations, emphasizing the multiplication process.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F87020c12-9fad-41df-8977-4681e6b0c96c%2F82cb1eb4-e404-4129-a143-cdf5fec3c780%2Fm0ahh0g_processed.jpeg&w=3840&q=75)
