Given that vector 𝐀 is equal to
negative one, negative eight, find three 𝐀.
Multiplying a vector by any real
number, as in this case, is known as scalar multiplication. In order to perform scalar
multiplication, we multiply each component of the vector by the scalar. In this question, we need to
multiply the vector negative one, negative eight by three. Multiplying a positive number by a
negative number gives a negative answer. Therefore, three multiplied by
negative one is negative three. Three multiplied by negative eight
is equal to negative 24. Three multiplied by the vector 𝐀
or the vector three 𝐀 is equal to negative three, negative 24.
