Question

Find the rank of the matrix $\left[\begin{array}{ccc}1&0\\0&0\end{array}\right]$

Answer 1

Answer:

Rank of given matrix is 1.

Step-by-step explanation:

To find the rank of the matrix,we must eliminate the rows as much as possible,or we can calculate linearly independent rows.

here in the given matrix  

$\left[\begin{array}{ccc}1&0\\0&0\end{array}\right]$

as it is clearly shown that 2nd row is completely  zero.

here we need not to calculate anything,because by elementary  row operation  we cannot reduce it further.

So,the rank of given matrix is one.
