It is an irrational number with an infinite decimal expansion that never repeats.

Given that the reals are uncountable (which can be shown via Cantor diagonalization) and the rationals are countable, the irrationals are the reals with the rationals removed, which is uncountable.(Or, since the reals are the union of the rationals and the irrationals, if the irrationals were countable, the reals would be the union of two countable sets and would have to be countable, so the ...Irrational Numbers Symbol. Generally, we use the symbol "P" to represent an irrational number, since the set of real numbers is denoted by R and the set of rational numbers is denoted by Q. We can also represent irrational numbers using the set difference of the real minus rationals, in a way $\text{R} - \text{Q}$ or $\frac{R}{Q}$.Oct 15, 2022 · The most common symbol for an irrational number is the capital letter “P”. Meanwhile, “R” represents a real number and “Q” represents a rational number. Sometimes the set of irrational numbers is R-Q or R|Q. Examples of Irrational Numbers.

Any number that can be represented or written in the p/q form, where p and q are integers and q is a non-zero number, is a rational number. Example: 12/5, -9/13, 8/1. On the other hand, an irrational number cannot be stated in p/q form, and its decimal expansion is non-repeating and non-terminating. Example: √2, √7, √11.If x = 1 then x 2 = 1, but if x = –1 then x 2 = 1 also. Remember that the square of real numbers is never less than 0, so the value of x that solves x 2 = –1 can’t be real. We call it an imaginary number and write i = √ –1. Any other imaginary number is a multiple of i, for example 2 i or –0.5 i. Jun 8, 2023 · Irrational numbers are non-terminating and non-recurring decimal numbers. So if in a number the decimal value is never ending and never repeating then it is an irrational number.
