Answer :
Answer:
3
Step-by-step explanation:
The scalar product (also known as the dot product) of two vectors a and b is calculated by multiplying the components of the vectors and then summing those products. For vectors a = [1, 0, 2] and b= [1, -2, 1], the scalar product a.b is computed as follows:
a.b = (1x1) + (0 x -2) + (2 x 1)
a.b = 1 + 0 + 2
a.b = 3
So, the scalar product a.b is 3.
