Question——问题 1:
a,b,c are positive integers.
Slove: a*a+b*b+c*c=2*a*a*b*b
a,b,c是正整数。
解方程:a*a+b*b+c*c=2*a*a*b*b
我第一眼看到這問題時好像很眼熟
At the first sight I though this question was familiar
好像是在projecteuler的一條問題,後來發覺看錯了 >>點我<<
I thought it's a question in projecteuler, but I took a mistake instead >>Click me<<
由於我不懂電腦的programming,我只好用計算機計了...
As I don't know computer programming, I can only use calculator...
以下是計算機程式 (CASIO fx-50FH) :
Below is calculator program (CASIO fx-50FH) :
Lbl 1:2A^2B^2-A^2-B^2->C:C^-.5->C:C=0=>Goto 3:Fix 0:Rnd(C)->D:C=D=>Goto 2:Norm 1:Lbl 3:B+1->B:B>A=>1->B:B=1=>A+1->A:Goto 1:Lbl 2:A,,B,,C,,
不出一秒便出現了 a=3 b=3 c=12
Not until I waited a second did the calculator show up a=3 b=3 c=12
我才發覺被騙了 人手計不是更快嗎!?
Then I realized I was faked... Isn't calculating by manpower faster!?
心有不服 我便改了問題-- abc不可以同等
I was furious, so I changed the question-- a, b, c are not equal
Lbl 1:2A^2B^2-A^2-B^2->C:C^-.5->C:C=0=>Goto 3:Fix 0:Rnd(C)->D:C=D=>Goto 2:Norm 1:Lbl 3:B+1->B:B>=A=>1->B:B=1=>A+1->A:Goto 1:Lbl 2:A,,B,,C,,
最後得出 a=111 b=15 c=2352
Eventually I got a=111 b=15 c=2352
答完了 其實我不用mod...
Answered. Actually I don't need mod...
但如果可以的話請幫我recheck?
But if possible can you please help recheck?
此外我想這廢文quote在你的首post裡 >v<
In addition I would like to have this trash post quoted in your first post >v<
謝謝~
Thanks~
