Find all positive integers ( n ) such that ( n^2 + 1 ) divides ( n! ).
[ \fracBEEA \cdot \fracAFFC \cdot \fracCDDB = 1 ]
However, we need to consider the restrictions $1 \le x_i \le 5$. rmo 1993 solutions
Thus the actual known inequality from RMO 1993 had a different constant. Without the exact original, we stop here.
The 1993 Regional Mathematical Olympiad (RMO) remains a significant milestone for students preparing for the Indian National Mathematical Olympiad (INMO) . The paper features a classic mix of geometry, number theory, and combinatorics, challenging students to think beyond standard school formulas. Find all positive integers ( n ) such
This is a classic ham-sandwich/pigeonhole variant.
Find the number of positive integer solutions to the equation $x_1 + x_2 + ... + x_n = 10$ where $1 \le x_i \le 5$ for each $i$. Thus the actual known inequality from RMO 1993
We can tilt line slightly to avoid points exactly on it, except the one we pivot around. Thus a line exists with at most floor(1993/2) points on each side.
Solve the equation $x^3 - 3x^2 + 4x - 2 = 0$.
