12/3=4
1122/33=34
111222/333=334
11112222/3333=3334
……
可見,有n個(gè)1和n個(gè)2的數(shù),除以n個(gè)3的數(shù)后,結(jié)果為n位數(shù),個(gè)位是4,其余為均為3.
所以
1111••••(2007個(gè))12222222(2007個(gè)) \3333333(2007個(gè))=33……334 (有2006個(gè)3)
計(jì)算:1111••••(2007個(gè))12222222(2007個(gè)) \3333333(2007個(gè))等于
計(jì)算:1111••••(2007個(gè))12222222(2007個(gè)) \3333333(2007個(gè))等于
