請放入適當符號，令下列數式成立5 5 5 5 5 = 24 (5*5) - 5^(5-5) = 25 - 5^0 = 25 - 1 = 24 [quote]原帖由 [i]yamits[/i] 於 2009-7-17 12:00 AM 發表 [url=http://www.26fun.com/bbs/redirect.php?goto=findpost&pid=3207898&ptid=205677][img]http://www.26fun.com/bbs/images/common/back.gif[/img][/url]
(5*5) - 5^(5-5) = 25 - 5^0 = 25 - 1 = 24 [/quote]
你條式都好複雜wor，要用到次方，但正確答案並唔係呢個，係無需用到次方 (5*5*5-5)/5 = (125-5)/5 = 120/5 = 24 [quote]原帖由 [i]shamanking19[/i] 於 2009-7-17 12:18 AM 發表 [url=http://www.26fun.com/bbs/redirect.php?goto=findpost&pid=3207917&ptid=205677][img]http://www.26fun.com/bbs/images/common/back.gif[/img][/url]

複雜就等於“唔正確”﹖﹖
其實你係唔係想話[u]答案係多過一個[/u]﹐但係[u]你自己個答案[/u]係無用到次方﹖ 問題係 <適當符號> 你o個個當然得啦!
除非問題改為 only +-*/ 啦
