Answer:

Explanation:

For the multiplication of two matrices, number of columns in 1st matrix should be equal to the number of rows of the 2nd matrix.

In the given question,

1st matrix →
\begin{bmatrix}2 & 8 & 1\\ 0 & 5 & -2\end{bmatrix}

Number of columns in this matrix = 3

2nd matrix → [5 2 1]

Number of rows in this matrix = 1

Therefore, number of columns in 1st matrix are not equal to the number of rows in the 2nd matrix.

Therefore, multiplication of matrices given in the picture is "Impossible".
