Question

How is B related to A ??​

Answer 1

Answer:

The first row of B is the third row of A.

The second row of B is 2 times the second row of A.

The third row of B is 2 times the first row of A.

Therefore B = PA, where

$\displaystyle P=\left(\begin{array}{ccc}0&0&1\\0&2&0\\2&0&0\end{array}\right)$
