Icebreaker said: "The sum of two irrational numbers is rational iff the difference between the sum and one of the irrational numbers is irrational." This can be re-worded as: "The sum of the two irrational numbers is rational iff the sum of the two irrational numbers is rational." Seems like redundancy to me.

WebSince R is a eld with an absolute value, we can de ne a Cauchy sequence (x n) of real numbers just as we did for rational numbers (now each x n is itself an equivalence class of Cauchy sequences of rational numbers). Corollary 1.13. Every Cauchy sequence of real numbers converges to a real number. Equivalently, R is complete. Proof. city of uhland zoning ordinance

WebAnswer (1 of 3): For those who need a concrete answer quickly: Yes. For any x, consider \log_x(2) and \log_x(3). Their ratio is \log_2(3), which is irrational (as no power of 2 is also a nontrivial power of 3). Thus, out of \log_x(2) and \log_x(3), at least one is … http://stat.math.uregina.ca/~kozdron/Teaching/Regina/305Fall11/Handouts/QisdenseinR.pdf city of tyler water utilityWebrational numbers.
