1. 定義 Lx(y)=x+1/y,Lx ^2(y)=Lx(Lx(y)),Lx^(n+1) (y)=Lx(Lx^n(y)) n is inter if Lx^6(x)=p(x)/q(x),而p(x)&q(x)為整數係數多項式 sol 1/Lx^(x) 2. 试为同餘方程組 2x≡1(mod 3) 3x≡1(mod 5) 5x≡1(mod 8) 求最小正整數解 3. 为同餘方程組1050601x≡-1(mod 10610040) 求最小正整數解更新: 點名者: 衍豐膠人至上主義者魔龍帝齊格益力多知識就是力量 STEVIE-G? 翻雷滾天風卷殘雲 ★幸運之星★☆不求名利?只求學問☆ myisland8132 Gabriella Montez 飛天魏國大將軍張遼 S cecimak1995 部分答問會轉用副戶，多謝各位好友支持！匿名俄羅斯方塊出現Ｎ字方塊時。都意外的難放呢～ [T] Roger╭★☆﹡暫休三天[T] [T ] is from Taiwan -Miruru623 20110206 更新 2: LU: ↗ Yogi? 兔氣揚眉～～ VIc doraemonpaul Chui-hing Den[T] 更新 3: LamTerry ( 小學級 1 級 ): maybe you are the first one but let me check about 1hr...or you will lose

我唔係點名者....但我識答BOR 得唔得先 1)Lx(X)=x+(1/x) Lx^2(X)=Lx(x+1/x)=x+1/x+1/x=x+x/x^2+1=(x^3+2x)/(x^2+1) ......... Lx^6(x)=x+[(x^5+4x^3+3x)/(x^6+5x^4+6x^2+1)]=[(x^7+6x^5+10x^3+4x)/(x^6+5x^4+6x^2+1)] so, 1/Lx^6(X) =[(x^6+5x^4+6x^2+1)/(x^7+6x^5+10x^3+4x)] 2)留意 2x=1(mod3)X40 3x=1(mod5)X24 5x=1(mod8)X15 ................ 80x=40(mod120).................(1) 72x=24(mod120).................(2) 75x=15(mod120).................(3) 2X[(3)-(2)]-[(1)-(3)]: 2X[3x=-9(mod120)]-[5x=25(mod120)] [6x=-18(mod120)]-[(5x=25(mod120)] x=-43(mod120)=77(mod120) answer:77 3)10610040x=0.................(1) 1050601x=-1......................(2) (1)-(2)X10: 10610040x=0 10506010x=-10 ----------------------- 104030x=10...................(3) (2)-(3)X10: 1050601x=-1 1040300x=100 ----------------------- 10301x=-101.....................(4) (3)-(4)X10: 104030x=10 103010x=-1010 ------------------------ 1020x=1020..........................(5) (4)-(5)X10: 10301x=-101 10200x=10200 -------------------------- 101x=-10301.......................(6) (5)-(6)X10: 1020x=1020 1010x=-103010 ----------------------- 10x=104030......................(7) (6)-(7)X10: 101x=-10301 100x=1040300 ---------------------- x=-1050601 so x=-1050601(mod 10610040) 最少正整數解x=10610040-1050601 =9559439
