Answer 1

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the matrix is not given.

The general form of a matrix is:

$b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right]$

Where m and n represent the $number\ of\ rows\ and\ columns$ respectively.

Notice the position of b11

This means that b11 is at the first column and first row.

Take for instance matrix b is:

$b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]$

The element at the first row and first column is 1.

Hence

$b_{11} = 1$
