Relationship Between AM and GM
For any two positive numbers, the arithmetic mean (AM) and geometric mean (GM) are not independent — they follow a strict and beautiful inequality. The AM is always greater than or equal to the GM, with equality only when the numbers are equal. This relationship, , is one of the most powerful tools in mathematics, forming the bedrock for many inequality proofs and optimization problems. Under …
