There is no specific symbol. The symbol for real numbers is R and that for rational numbers is Q so you could use R \ Q.
There is no representation for irrational numbers: they are represented as real numbers that are not rational. The set of real numbers is R and set of rational numbers is Q so that the set of irrational numbers is the complement if Q in R.
When any value satisfies the equation, you would simply state "all real numbers." There is a symbol for it, and even though it is difficult to explain, I will attempt to. It is simply an R with an extra line making it kind of look like |R, but it's connected to the furthermost left parallel line. I hope that helps!

False. Irrational numbers are real numbers.
There is no specific symbol. The symbol for real numbers is R and that for rational numbers is Q so you could use R \ Q.
It is R, which stands for Real. Really!
There is no special symbol.The set of rational numbers is denoted by Q and the set of real numbers by R so one option is R - Q.
The set of all real numbers (R) is the set of all rational and Irrational Numbers. The set R has no restrictions in its domain and so includes (-∞, ∞).
It is called Real. It's symbol is R$.
The currency ofBrazil is the Brazilian Real (plural being Reais). The symbol for it is R$.
The set of all real numbers (R) is the set of all rational and irrational numbers. The set R has no restrictions in its domain and so includes (-∞, ∞).
The main subsets are as follows:Real numbers (R) can be divided into Rational numbers (Q) and Irrational numbers (no symbol).Irrational numbers can be divided into Transcendental numbers and Algebraic numbers.Rational numbers contain the set of Integers (Z)Integers contain the set of Natural numbers (N).
No. Cruzeiro Real is an outdated currency. We now use the Real. (R$ is the symbol for it)
There is no representation for irrational numbers: they are represented as real numbers that are not rational. The set of real numbers is R and set of rational numbers is Q so that the set of irrational numbers is the complement if Q in R.
Real numbers are a proper subset of complex numbers. In fact each complex number, z, can be represented as z = x +iy where x and y are real numbers and i is the imaginary square root of -1.Thus the set of complex numbers is the Cartesian product of two sets of real numbers. That is, C = R x R where C is the set of complex numbers and R is the set of real numbers. Limitations of this browser prevent me from writing that in a mathematically precise and more helpful fashion.
Yes, since the set of real numbers can be expressed as a countable union of closed sets.In fact if we're talking about subsets of the real numbers (R), then by definition R is in all sigma-algebras of R including the Borel sigma-algebra, and so is a Borel set.
