Question

find the rank of the following matrices [ 1 2 0 -2][3 4 1 2] [-2 3 2 5]​

Answer 1

Answer:

Convert the matrix into row echelon form. Rank of a matrix =no.of non zero rows in row echelon form matrix. Eg: A = [1 0 0 0 1 0 0 0 1] Then, the rank of matrix p(A)= 3 as the matrix has 3 non zero rows and it is row echelon form.
