    Answer:

    (8,90°)

    Step-by-step explanation:

    To get this answer, you multiply the r values together to get 2*4 = 8. At the same time, you add the theta angles to get 45° + 45° = 90°

    The general rule is that if A = (r,theta) and B = (s,phi) then

    A*B = (r*s,theta+phi)

    where the point (s,phi) is a polar form point.
