Two basic facts you should know (and use them in this exercise):DWill said:Homework Statement
Let A and B be two n x n matrices that are related by the equation (P^-1)(A)(P) = B, where P is another n x n matrix. Prove that det(A) = det(B).

The Attempt at a Solution
I'm thinking the first step might be to come up with general forms of A and B that are related by the above equation? I've been trying to do that and not been successful so far. Any ideas? thanks
Linear algebra is a branch of mathematics that deals with linear equations and their representations in vector spaces. It involves the study of linear transformations, matrices, and systems of linear equations.
Linear algebra has numerous applications in various fields such as physics, engineering, computer science, economics, and statistics. It is used for solving systems of equations, analyzing data, and creating computer graphics, among others.
The basic concepts of linear algebra include vectors, matrices, vector spaces, linear transformations, eigenvalues and eigenvectors, and determinants. These concepts are used to solve linear equations and represent real-world problems mathematically.
A linear algebra problem is a mathematical problem that involves solving linear equations or systems of linear equations using various methods and techniques from linear algebra. These problems often require manipulating matrices, vectors, and other concepts from linear algebra to find a solution.
Some common techniques for solving linear algebra problems include Gaussian elimination, matrix multiplication, inverse matrices, and vector operations. Other techniques, such as determinants and eigenvalues, are used for more advanced problems. The choice of technique depends on the specific problem at hand.
