Do you have any idea what the notations "axb" and "a.b" mean? Please show some attempt at the problem so we will have an idea what you do and do not understand about the problem and will know what hints would be best.

(Joppy, Lucky123 posted another thread titled "Vector" but it was a different problem.)

Also Lucky, you seem to have "." at the end of several of the choices. Is this the same . you use for the dot product, or is it just a full-stop?
