Question: If the equation det A = det Bholds for two n 脳 n matrices A and B , is A necessarily similar toB?

Short Answer

Expert verified

Therefore, A and B are not similar.

Step by step solution

01

Matrix Definition 

Matrix is a set of numbers arranged in rows and columns so as to form a rectangular array.

The numbers are called the elements, or entries, of the matrix.

If there are m rows and n columns, the matrix is said to be a 鈥渕 by n鈥� matrix, written 鈥� m 脳 n.鈥�
