Irrational number

Postby Andreas on Fri May 02, 2014 6:35 pm


How can I prove that the number formed by concatenating the primes in order i.e. 0.235711131719.. is irrational.


I know I have to demonstrate that it has no period, but I'll be so thankful if someone can explain very clear, including all cases.

What have you accomplished, including what you've already been given here? For instance, what "cases" have you determined there to be?
