The scalar product (also known as the dot product) of two vectors is calculated by multiplying their corresponding components and then adding those products together.

Given vectors A = 2i + 5k and B = 3j + 4k, we can see that vector A has no j component and vector B has no i component. Therefore, when we multiply the corresponding components, these will result in zero.

The scalar product of A and B is therefore:

A.B = (2*0) + (0*3) + (5*4) = 0 + 0 + 20 = 20.
