Question
**Matrix Determinant Calculation**

**Problem Statement:**

For matrix \( C = \begin{bmatrix} 1 & 3 & 5 & 7 \\ 0 & 1 & 2 & 3 \\ 4 & 5 & 6 & 7 \\ 0 & 1 & 0 & 1 \end{bmatrix} \), compute the determinant \(|C|\) or \(\det C\).

**Instructions:**

**Part 1:**  
Use the cofactor expansion technique discussed in class to expand the determinant. Express the expansion with the notation introduced during lectures. You have the option to perform the final calculations using either \(3 \times 3\) determinants or \(2 \times 2\) determinants. Ensure to show all steps of your work.

**Part 2:**  
Apply Gaussian Elimination with determinants to find \(|C|\). Utilize \(\rho\) notation to specify the operations executed at each step.
