Best Answer

Every real number is either rational, or irrational. Examples of Irrational Numbers include:

* The square root of any positive integer, except that of a perfect square.

* The number pi.

* The number e.

* Any of the above, multiplied by or added to a rational number - for example 2 x pi, 2/3 times the square root of 2, etc.

* An expression like 10 to the power x is irrational for most values of x.

The set of real numbers is defined as the union of all rational and irrational numbers. Thus, the irrational numbers are a subset of the real numbers. Therefore, BY DEFINITION, every irrational number is a real number.

Real numbers can be rational or irrational because they both form the number line.

There is no such number.

No, a real number could also be a rational number, an integer, a whole number, or a natural number. Irrational numbers fall into the same category of real numbers, but every real number is not an irrational number.

No. The real number line corresponds to rational AND irrational numbers.

A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).

No it cannot. Irrational means "not rational".

An irrational number is a real number that is not rational.

All irrational numbers are Real numbers - it's part of the definition of an irrational number. Imaginary numbers are neither rational nor irrational. An example of a number that is both Real and irrational is the square root of two. Another example is the number pi.

Yes it will be. The set of real numbers can be divided into two distinct sets: rational and irrational. So if it is not rational, then it is irrational.

All numbers are real. A number being irrational just means that is does not have a definite end.
