Multiply the following matrix with the given scalar.

3[9 8]
[10 4]
[6 5]

First, we multiply each element of the matrix by the scalar 3:

3[9 8] = [27 24]
3[10 4] = [30 12]
3[6 5] = [18 15]

Therefore, the result of multiplying the matrix [9 8; 10 4; 6 5] with the scalar 3 is the matrix [27 24; 30 12; 18 15].
