【No. 1110】Zorome (ゾロ目 - Repdigit)

Jan 1, 2018 16:56
Happy New Year.

Today is January 1st, and this is 1111th post.

When same numbers line up like this, it is called ゾロ目 (zorome) in Japanese.

"Zorome" was created by emphasizing the word, 揃い目 (soroime).

Here, the 揃い (soroi) means "to much up" or "to get together," and the 目 (me) means "pips of a dice."

Because of this, "zorome" originally meant that two dices show the same number.

These days, it has come to mean that same numbers line up.

Incidentally, there is no perfect power in zorome natural numbers composed of two or more digits (e.g., 111, 3333).
ゾロ目

あけましておめでとうございます。

今日は1月1日、そしてこれは1111回目の投稿です。

このように同じ数字が並ぶことを、「ゾロ目」と言います。

「ゾロ目」は、「揃い目」が強調された言葉です。

ここで「目」は、サイコロの目を意味します。

もともと「ゾロ目」は2つのサイコロの目が揃うことを意味していました。

これが転じて現在では、同じ数字が並ぶことも意味するようになったというわけです。

ちなみに、2桁以上のゾロ目の自然数で、累乗数のものは存在しません。

I'd be very interested to see a proof of that last statement ;)

Thank you very much for correcting my post!
According to the Wikipedia, you can see the proof of that in an article, "On the Diophantine equation a(x^n-1)/(x-1)=y^q," written by Yann Bugeaud.

Thanks! I haven't found the specific paper yet, but it looks like related works contain a lot more math than I learned in college ^^;
