- PROVE: Arithmetic-Geometric Mean Inequality
If a1, az, ..., a, are nonnegative numbers, then their
a, + az +... + a,
arithmetic mean is
and their geometric
mean is Vajaz ...ap. The arithmetic-geometric mean
inequality states that the geometric mean is always less than
or equal to the arithmetic mean. In this problem we prove
this in the case of two numbers x and y.
(a) If x and y are nonnegative and Is y, then xs y².
[Hint: First use Rule 3 of Inequalities to show that
x's xy and xy s y².]
(b) Prove the arithmetic-geometric mean inequality
