(a) Find the maximum value of
given that x1, x2, . . . , xn are positive numbers and x1 + x2 + . . . + xn = c, where c is a constant.
(b) Deduce from part (a) that if x1, x2, . . . , xn are positive numbers, then
This inequality says that the geometric mean of n numbers is no larger than the arithmetic mean of the numbers. Under what circumstances are these two means equal?
