Vector a (4; -1) vector b (-2; -5) find vector a multiplied by wind b.

To search for the question posed in the original task, we will be guided by a set of rules and formulas common in mathematical science that regulate the order of performing arithmetic operations with the coordinates of vectors. In accordance with the general rule, to find the product of vectors, it is necessary to multiply the values of their coordinates. With that said:

a * b = (4 * (-2)); ((-1) * (-5)) = (-8; 5).
