(2:0,5)•1,3

To calculate the product of the vector (2:0.5) and the scalar 1.3, you multiply each component of the vector by the scalar.

The calculation is as follows:

1. For the first component: \( 2 \times 1.3 = 2.6 \)
2. For the second component: \( 0.5 \times 1.3 = 0.65 \)

Thus, the result of the multiplication is the vector:

\[ (2.6, 0.65) \]
