Answer 2

We have been given the matrix m as m = [874][205].

We can rewrite this matrix as

$m=\begin{pmatrix}8 &7&4\\2&0&5 \\\end{pmatrix}$

Now, we need to the find $m_{12}$

It means we need to find the entity that is present in the first row and the second column.

From the above matrix, we can see that 7 is in the first row and the second column.

Therefore, we have

$m_{12}= 7$
