Arithmetic - Geometric Mean Inequality (AM - GM)

For any non - negative real numbers a₁, a₂,..., a n, we have: (a₁ + a₂ + ... + a n)/(n) ≥ [n] a₁ a₂... a n Equality holds if and only if a₁ = a₂ = ... = a n. E…

Formula and explanation

For any non - negative real numbers a₁, a₂,..., a n, we have: (a₁ + a₂ + ... + a n)/(n) ≥ [n] a₁ a₂... a n Equality holds if and only if a₁ = a₂ = ... = a n. Explanation: The arithmetic mean is always greater than or equal to the geometric mean.
