What number is r

9 Answers. Q Q is dense in R R, so Q + 2–√ Q + 2 is dense in R + 2–√ = R R + 2 = R. Since Q + 2–√ Q + 2 is a subset of the irrationals, we conclude that the irrationals are also dense in R R. By the density of rational numbers, there exists a rational number r ∈ (x, y) r ∈ ( x, y).
