@John They have to have some sort of great intelligence to get this far into the integration bee, don't see why there was any need for this comment lmao.
@John Understanding that these guys are judged to be smart enough to compete during an intergration bee is indeed very short sighted, but yet you were too blind to see that...
The answer of Q.4 should be 5 * 10^18 * ln(1001/999) ,which is equal to the answer written in decimal. Luke get almost right answer but he got ln(1003/1001) which is the only part wrong in the answer. The arbiter said there is no 5, but there is. We can't solve log on the board with time limit.
Not only did Luke win this, he was also a multiple time winner of MATHCOUNTS internationals and many more competitions. He truly is very capable of many things.
I'm surprised by the fact no one in the video or even in the comment section realised that, in 21:16 , they both got the answers correct! coz if you simplify their answers, you'll get the same answer as that given by the MIT. It's a shame to judge the answers as wrong just because they were not written exactly same or it should not be 'a multiple of 5'. Integral answers often exist in many forms. They both should have gotten a point for that.
Honestly, problems are doable and is not super hard. However it's important you finish in time before other person and dont make blunder under time pressure

F(Y) = 1/20 x ln | (Y-25) / (Y-23) | so F(INFINITY) = ln 1 = 0 and -F(2^10=1024) = ln(1001/999) = 2 x (10^-3 + 10^-9/3 + 10^-15/5 + 10^-21/7 + ...) times 10^20/20 = 10^19/2 (2s cancel next).
