For this case we have the following vectors:

The dot product of two vectors is a scalar.
The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
For the product point of the vectors a and b we have:
Answer:
The product point of the vectors a and b is:
The answer is D because if you go to 150 and line it up you will get 7 as you answer
multiply all numbers together:
3*6*4*3 = 216 combinations
