#0, Irrational numbers
Posted by C. Reineke on Jun-24-10 at 08:00 AM
Dear Alex,

yesterday I came across your page:

http://www.cut-the-knot.org/do_you_know/irrat.shtml

Noone seems to notice the fact that (for example!)

log4 is irrational and sqrt(10) is irrational, but

sqrt(10)^log4=10^log2=2 is rational.

Where is the problem? Or am I wrong?

Kind regards

Chris
