We are given two matrices $A$ and $B$, where $A = \begin{bmatrix} 2 & 1 & 0 \\ 7 & 2 & 8 \\ 1 & 0 & 4 \end{bmatrix}$ and $B = \begin{bmatrix} 1 & 1 & 4 & 0 \\ 8 & 3 & 1 & 1 \\ 1 & 3 & 2 & 0 \end{bmatrix}$. We need to find the matrix product $BA$.

1. Problem Description

We are given two matrices AA and BB, where
A=[210728104]A = \begin{bmatrix} 2 & 1 & 0 \\ 7 & 2 & 8 \\ 1 & 0 & 4 \end{bmatrix} and B=[114083111320]B = \begin{bmatrix} 1 & 1 & 4 & 0 \\ 8 & 3 & 1 & 1 \\ 1 & 3 & 2 & 0 \end{bmatrix}.
We need to find the matrix product BABA.

2. Solution Steps

The matrix BB is a 3×43 \times 4 matrix and AA is a 3×33 \times 3 matrix. For the matrix product BABA to be defined, the number of columns in BB must equal the number of rows in AA. However, BB has 4 columns and AA has 3 rows. Thus, the product BABA is not defined, i.e. impossible.

3. Final Answer

IMPOSSIBLE
