Matrices and determinant properties?

In summary, a matrix is a rectangular array of numbers, symbols, or expressions used to represent and manipulate linear transformations and systems of linear equations. Matrices have properties such as addition, subtraction, scalar multiplication, and inverse, as well as commutativity, associativity, and distributivity. A determinant is a scalar value that can be calculated from the elements of a square matrix and is used to determine important properties of a matrix, such as invertibility and the number of solutions to a system of linear equations. Determinants also have properties such as linearity, multiplicative property, and the property that it is equal to the product of the eigenvalues of a matrix. Matrices and determinants are closely related, with the determinant of

The Attempt at a Solution


I tried to see if the problem has any properties with determinants that i can apply but the properties i learned didn't involve the use of adjoint matrices so I'm kind of stumped on this one.
Any hints would be grateful. Thank you in advance

1. What is a matrix?

A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. It is used to represent and manipulate linear transformations and systems of linear equations.

2. What are the properties of matrices?

Matrices have several properties, including addition, subtraction, scalar multiplication, matrix multiplication, and inverse. They also have properties such as commutativity, associativity, and distributivity.

3. What is a determinant?

A determinant is a scalar value that can be calculated from the elements of a square matrix. It is used to determine important properties of a matrix, such as invertibility and the number of solutions to a system of linear equations.

4. What are the properties of determinants?

Determinants have properties such as linearity, multiplicative property, and the property that it is equal to the product of the eigenvalues of a matrix. They are also used to calculate the area or volume of a parallelogram or parallelepiped.

5. How are matrices and determinants related?

Matrices and determinants are closely related, as the determinant of a matrix can be used to determine important properties of that matrix, such as its invertibility and the number of solutions to a system of linear equations. Matrices are also used to represent and manipulate linear transformations, which can be described using determinants.
