To find the product of the matrix and the vector, we can perform the matrix multiplication.
The given matrix is:
[2 1]
And the given vector is:
[3]
To perform the matrix multiplication, we need to multiply each element of the matrix by the corresponding element of the vector and sum the results.
So,
2 * 3 + 1 * 0 = 6 + 0 = 6
Therefore, the product of the matrix and the vector is 6.
