These are no fractions, are they? (Posted on 2006-09-05) Difficulty: 3 of 5
You are probably quite certain that the following numbers are irrational. But can you prove it?

a = 0.149162536496481...

b = 0.2357111317192329...

c = 0.1248163264128256...

Obviously, a is

266060029582368375943402260274 / 1783692043803805672104863371093
= .14916253649648123874...

and therefore not irrational.

As you see, I got even some of the digits right which you didn't even give in the problem, so it has to be correct.
