Self-powered numbers


We recently asked the not-so-complicated question: why is the
387 420 489
number interesting?
The answer is: because it is the largest number that can be written with two digits:
387 420 489 = 99
There are people who, if they are not in a good mood, do not see anything interesting in anything. They can be heartily regretted. Let’s keep up our good humor and try now to see something more interesting in this issue!
Well, I’m not sparking interest: the amazing thing is that 99 is properly written out of nine digits. Could this be typical of nn type numbers? What a pleasant start: 11 is a single digit. Capture us with excitement…
But the series doesn’t go on like that, it’s stuttering locally. 22 also consists of one digit. This disadvantage can no longer be worked out – until 8. 88 consists of 8 digits.
For 1010, 10 zeros is enough, but it still need 11 digits. From now on, however, there is no stopping. Above this, to describe nn, it would need an increasing number of digits that n. However, this sequence does not give a dizzying progression. Monotonously growing but gently growing. We do not give examples, but show the first 80 values. Interesting sequence. Unless you're in the mood.
