The number of occurrences of each digit from zero to nine within the first [math] n [/math] digits of [math] \sqrt{2} [/math] approaches to [math] \dfrac{n}{10} [/math] as [math] n [/math] approaches infinity.

Can you prove this?

disproof: in base 4

Base 10 is special case. The generalized version of my conjecture is:

>The number of occurrences of each digit from zero to [math] b [/math] within the first [math] n [/math] digits on [math] \sqrt{2} [/math] in [math]\text{base-b}[/math] approaches to [math]\dfrac{n}{b}[/math] as [math] n [/math] approaches infinity.

By occurrence I mean the occurrence of one individual digit.

Proving that √2 is a normal number is extremely hard. Same for other irrational numbers such as π and e.

>> No.14758084

I did a test on base-7 with seven million digits. So each digit should occur a million times. Here's the data on each digit.

0: 1 000 251
1: 999 671
2: 999 517
3: 1 000 633
4: 998 591
5: 1 001 898
6: 999 484

zero isn't a number. Neither is "root 2"(expression)

It's proven not to be a number whatsoever.

Does a proof even exist for any of them?

based if true
based if false

pretty interesting

I wouldn't assume homogenaity for a given precision. Ie perhaps the first 10000 digits is spread uniformly between 0-9 but not 150000
