24を作るには??
MR.DKC (2002/11/02(Sat) 15:04:22)
「1」「5」「5」「5」の4つの数字で24を作る。
<ルール>
?@4つの数字は順番関係なく必ず1回使う。(2回以上使っても、1回も使わないというのは駄目)
?A使うのは四則演算
?B1の5乗とかは駄目。あくまで4つの数字を+−×÷を使って24にする。
最初に考えたのは「5×5−1の5乗=24」だったのですが、?Bのルールを後だしされ、駄目でした。このルールで出来ますか????
P.S.もしもできたなら、次は3、3、8、8で24を作ってください。
御願いします。

1、5、5、5であれば、
1÷5=1/5
5−1/5=24/5
24/5×5=24
3、3、8、8であれば、
8÷3=8/3
3−8/3=1/3
8÷1/3=24
ですね。
