Given below are certain facts about distance and displacement. Choose the option which gives the correct information about the two. A. It is a scalar quantity. B. It is a vector quantity. C. It can be zero. D. It cannot be zero. E. The quantity that is scalar is either equal or greater in magnitude than the quantity that is vector.
Four  matrices  M1, M2, M3 and M4 of dimensions p×q, q×r, r×s and s×t respectively can be multiplied in several ways with different number of total scalar multiplications. For example when multiplied as [(M1 × M2) × (M3 × M4)] the total number of scalar multiplications is  pqr + rst + prt. When multiplied as [((M1 × M2)× M3)) × M4], the total number of scalar multiplications is pqr + prs + pst. If p = 10, q = 100, r = 20, s = 5 and t = 80, then the minimum number of scalar multiplications needed is:
