kozerog [31]

Answer:

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

Step-by-step explanation:

Let's do the multiplication AB.

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

then the first row of A is= (1 0) by the first column of B= (0 0) is equal to zero.

the first row of A is= (1 0) by the second column of B= (0 1) is equal to zero too because 1.0+0.1=0.

the second row of A is= (0 0) by any colum of B is equal to zero too.

So we have found an example that works!
