Talk:1981 IMO Problems/Problem 3

Although it is a trivial detail (in hindsight anyway), I note that two sources (The IMO Compendium and Kalva), as well as AoPS (whose problem statement and solution are both identical to Kalva's), ask to find the maximum value of $\displaystyle m^2 + n^2$, but what is, as far as I know, the official IMO site asks rather for the maximal value of $\displaystyle m^3 + n^3$. I went with Kalva and the IMO Compendium, for although I do not trust Kalva for the original wording, I do not think that both it and the IMO Compendium would have changed it. It makes practically no difference anyhow, except for the fact that someone might conceivably try to solve the problem using algebraic manipulations. —Boy Soprano II 23:10, 28 October 2006 (EDT)
