You have to look for the repeating pattern of units digits for each problem.\n\n1998^1 ends in 8\n1998^2 ends in 4  (8X8=64)\n1998^3 ends in 2\n1998^4 ends in 6\n1998^5 ends in 8 so it's starting to repeat.  It repeats every 4 so 1998^1999 is the same as 1998^3, ends in a 2.\n\nNow for 1999^1998.\n1999^1 ends in a 9\n1999^2 ends in a 1 9X9 = 81\n1999^3 ends in 9  It's already repeating\n\nSo 1999^1998 ends just like 1999^2 did, with a 1\n\nFinally subtract these two end digits since that's all you care about: 2 - 1 = 1\n\nSo it ends in a 1

well we know the 3 space must be even, in order to avoid the last space resulting in another 5\n\nhmmm... i'l work on it, provided you're working as well!\n\n..and #3 mustn't be 0, to avoid another 0\n..lol i'd have had it if i had been home...i made a program to do it, and then left before i finished/ran it lol\n\nbut that, is of course, the correct asnwer, 396*45=17820\n\nhaha thanx for the challenge!

this is probably not a perfect answer but this site may give you some clues.\n\nhttp://www.gomath.com/Questions/question.php?question=4751\n\naltrnatively type 'prove v*v = 2gr*r/s+v0*v0-2gr' into a search engine and see what comes up.

16/24....it's really not that hard...you should be able to solve it on your own.\nps. you might want to simplify it down to 2/3.

Sorry, but your question is written very poorly.  You might want to try looking at how some of the other math questions are written out, then rewriting your questions so that it makes more sense.

Add them together and divide by 5.\n\nWow. I could seriously have you people do my homework for me. Every night. I'll type out the problems and see how you all do. :P JP

Well, you got me stumped!\n\n-------------------------------------\n\nI started working it out and got pretty far.\n\nThe above given information might be incorrect.  Maybe?  I don't know.\n\nI tried it several times.  I even double and triple checked my work!\n\n---------------------------------------------\n\nThis is as far as I got and then I got stumped:\n(D-E) (B+C) = (10J + AFGH) / A\n\n------------------------------------------------------\n\nGreat question!\n\nI look forward to the continuing discussion.\n\nI love the way you worded your question.  Right on!!!\n\nKeep those challenge questions coming!  ;o}
