So, x^(n/m) is irrational for any positive integers n and m. But, by continuity, for any positive rational number r, there must be some power p such that x^p=r. By the above, p can't be rational, so it must be irrational. As u/randomdragoon pointed out, this argument fails.What is the symbol for irrational? Irrational numbers are usually expressed as R\Q, where the backward slash symbol denotes 'set minus'.

Apr 28, 2022 · Every rational number (ℚ) can be expressed as one integer (p) over another integer (q): p/q where q cannot be 0. The rational numbers can be converted to decimal representation by dividing the top number (p) by the decimal number (q): p/q = p ÷ q. When q = 1, this produces the rational numbers: p/1 = p ÷ 1 = p which is just an integer; it ...

In short, the numbers that are not regular and cannot be represented by a fraction are irrational numbers. Note that not all square roots are irrational. For example, 4 is a rational number. The reason is that 4 is 2, as shown below.Irrational Numbers. These are numbers which, when written as a decimal, never end and never repeat. They cannot be expressed as fractions, so rational numbers and irrational numbers are separate sets. Examples of irrational numbers include √2 and π. There is no fixed symbol for irrational numbers.
