Question
![**Title: Calculating the Determinant of Matrices Using Row and Column Operations**
**Objective:**
Find the determinant of the given matrices using at least one row operation and at least one column operation.
**Matrices Provided:**
1. **Matrix A:**
\[
A = \begin{bmatrix}
-3 & -4 & 4 & -3 \\
11 & 3 & 7 & 1 \\
3 & 5 & -5 & 6 \\
-6 & -3 & 3 & -10 \\
\end{bmatrix}
\]
2. **Matrix B:**
\[
B = \begin{bmatrix}
5 & -10 & 10 & -8 & -8 \\
-2 & 6 & 5 & 1 & 1 \\
-2 & 6 & 5 & 4 & 4 \\
11 & 3 & -2 & 5 & 0 \\
0 & 1 & 4 & 7 & 7 \\
\end{bmatrix}
\]
**Instructions:**
To calculate the determinant of each matrix, apply a combination of row and column operations to simplify the matrices. This approach involves using elementary operations to aid in the calculation of the determinants, which can make the process more straightforward.
**Key Concepts:**
- **Row Operations:** Includes swapping rows, multiplying a row by a non-zero constant, and adding or subtracting the multiple of one row to another.
- **Column Operations:** Similar to row operations but applied to columns.
- **Determinant:** A scalar value that can be computed from the elements of a square matrix and encodes certain properties of the matrix.
**Note:** Applying these operations strategically will help transform the matrices into shapes that are easier for determinant calculation, such as triangular form, while ensuring all necessary computations for the determinant are accounted for.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F30f79184-3047-455a-b3d8-f2ad47623cdf%2Feaa511d4-0397-4257-9bed-f05d497d00d8%2F12p80h4_processed.jpeg&w=3840&q=75)
