Question

If a matrix A has all its minor of order r + 1 are zero then
A) rank of A greater than equal to r
B) rank of A equal to r
C) rank of A less than equal to r
D) none of these​

Answer 1

Answer:

The rank of a matrix is defined as (a) the maximum number of linearly independent column vectors in the matrix or (b) the maximum number of linearly independent row vectors in the matrix. Both definitions are equivalent. For an r x c matrix, If r is less than c, then the maximum rank of the matrix is r.
