back to boardlook this Posted by 连连 7 Aug 2008 07:40 I input test data: 100 200 3 3 Is the example right? 100 = 3^ 4 + 2 * (3^2) + 1
109 = 3^4 + 3^3 + 3^0 117 = 3^4 + 3^2 + 3^1 141 = 3 ^4 + 2* (3^3) + 2 * 3 which model is right ? or all right ? Edited by author 07.08.2008 08:27 Re: look this The models of 100 and 141 are wrong. The other two ones are right. Re: look this Posted by 连连 9 Aug 2008 22:56 the sum of exactly three integer degrees of number 3, why are models of 100 and 141 wrong? who can tell me why ? Edited by author 09.08.2008 22:57 Edited by author 09.08.2008 22:57 Re: look this Posted by bottles 21 Aug 2008 22:54 because the problem told us to do so Re: look this 100 = 3^4 + 2 * (3^2) + 1 141 = 3^4 + 2 * (3^3) + 2 * 3 This ones are incorrect because when you miltiply one of the degree by 2 It becomes 100 = 3^4 + 3^2 + 3^2 + 1 141 = 3^4 + 3^3 + 3^3 + 3 + 3 so, it's sums of 4 and 5 degees, not 3. Besides, it are to be different. Edited by author 26.08.2008 13:13 Re: look this thanks a lot, the qustions perplex me a long time, thank you |
