The document you've uploaded contains several exercises from a practice worksheet, focusing on matrix operations, determinants, and solving linear equations. Here’s a summary of the problems:

1. **Matrix Multiplication (AB ≠ BA):**
   - Exercises where you verify if matrix multiplication of two given matrices \(A\) and \(B\) is not commutative (i.e., \(AB \neq BA\)).

2. **Matrix Products:**
   - You are asked to calculate the product \(AB\) for given matrices \(A\) and \(B\).

3. **Determinants:**
   - The task is to calculate the determinant of several matrices.

4. **Solving Linear Equations:**
   - Solve systems of linear equations using both Cramer’s Rule and the Inverse Method.

5. **Rank of Matrices:**
   - Calculate the rank of matrices by using the determinant method, converting into echelon form, and calculating eigenvalues.

Would you like assistance with a specific problem or detailed solutions for one of the questions?

Here are five questions based on this worksheet:

1. How do you verify if \(AB \neq BA\) for two matrices?
2. What is the process for calculating the determinant of a matrix?
3. How is Cramer’s Rule used to solve a system of linear equations?
4. What is the significance of matrix rank, and how do you compute it?
5. How do you compute the eigenvalues of a matrix?

**Tip**: When performing matrix multiplication, remember that the order of multiplication matters—multiplying matrices in reverse order often yields different results.

The document contains several exercises related to matrix operations, including matrix multiplication, determinants, solving linear equations, and rank of matrices. How do you approach these problems?

This practice worksheet covers key matrix operations such as multiplication, determinants, solving systems of linear equations using Cramer's Rule and inverse methods, and computing matrix ranks. Topics are suitable for advanced high school or college students.
