It is irrational because one of the factors is irrational.

Reason: sqrt(23) is irrational and 5/6 is a nonzero rational. A nonzero rational times an irrational is irrational (if r is rational nonzero and x is irrational, then rx rational would imply x = (rx)/r is rational, contradiction). Hence (5/6)·√23 is irrational.
