Are irrational number integers?

No- integers are a kind of rational number and are not irrational. One well-known example of an irrational number is the square root of 2.


What is rational compared to irrational?

rational numbers can be represented as a ratio of integers such as 1/4 and irrational numbers can NOT. Square root of 2 is an irrational number.


Is the square root of 29 a rational or an irrational number?

The square root of 29 is an irrational number.


Is the square root of 8 a real number or a rational number or an irrational number or integers or a whole number?

The square root of 8 is irrational and real.


If you take the square root of an irrational number.Will it be irrational too?

Certainly. Otherwise, there would be a rational number whose square was an irrational number; that is not possible. To show this, let p/q be any rational number, where p and q are integers. Then, the square of p/q is (p^2)/(q^2). Since p^2 and q^2 must both be integers, their quotient is, by definition, a rational number. Thus, the square of every rational number is itself rational.


Some integers are not rational numbers?

All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.

Are the square roots of all positive integers irrational If not give an example of the square root of a number that is a rational number?

The square root of any positive square number is always rational as for example the square root of 36 is 6 which is a rational number.


Is the square root of 99 a rational number?

โˆš99 = Square root of 99 = Irrational. Rational # are able to be expressed as the ratio of 2 integers. i.e. โˆš25 = +5 5 = 5/1 = rational Irrational # can not be expressed as a ratio of 2 integers.


Is the square root of 14.4 rational or irrational?

It is irrational, because it is not a perfect square. For example, if you have a number that is perfect like the square root of 100, it would be 10, which is a rational number. An irrational number like 16.4 which would be a not so accurate result like 6.447583839, those are irrational numbers. Hope this helps!


What number is both rational and irrational?

None. A rational number is a number that can be written as the quotient of two integers where the divisor is not zero. An irrational number is a real number that cannot be written as the quotient of two integers where the divisor is not zero. Any given real number either can or cannot be written as the quotient of two integers. If it can, it is rational. If it cannot, it is irrational. You can't be both at the same time. The square root of -1 is not a real number and it cannot be written as the quotient of two integers, so it is neither rational nor irrational.


What are irrational and rational numbers?

A rational number can be expressed as a fraction a/b, where a and b are integers. This includes the integers themselves, that can be expressed as (number) / 1. An irrational number is one that can't be exactly expressed in this way. This includes the square roots of any integer that is not a perfect square; pi; and e - and a host of other numbers. There are more rational than irrational numbers (rational numbers are a countable infinity", and irrational numbers an "uncountable infinity"), but we usually deal mainly with rational numbers - or use rational approximations for the numbers we deal with.


If you get a whole number while doing square roots what would the answer be rational or irrational?

A rational number is a number that can be expressed as the division of two integers, while the divisor is not zero. An irrational number is any number that is not rational.Whole numbers are rational, because the divisor is 1. It has nothing to do with square roots.


What is irrational or rational?

In math, a rational number is one that can be expressed as the RATIO (or fraction) between two integers. This includes the integers themselves, and fractions such as 2/3, 7/5, -3/2, etc.An irrational number is one that can't be expressed exactly as a fraction. For example, the square root of 2 (indeed, the square root of any positive integer is either a whole number or an irrational number), pi, e, and combinations such as square root of 2 + 1, pi/4, etc. Outside of math, "rational" means something that makes sense; "irrational" is something that doesn't.


How to find rational numbers using arithmetic mean?

A rational number is one that is the ratio of two integers, like 3/4 or 355/113. An irrational number can't be expressed as the ratio of any two integers, and examples are the square root of 2, and pi. Between any two rational numbers there is an irrational number, and between any two irrational numbers there is a rational number.


Is the square root of 9 rational or irrational?

It is rational.The square root of 9 is 3 and it is a rational number


Is the square root of 09 an irrational number?

no the square root of 9 is 3 which is rational since it can be written as 3/1. remember a rational number is any number that can be written as a/b where a and b are integers.


Is 0.0125 a rational or irrational number?

Rational. An irrational number is something that cannot be written as a fraction of integers and since they can't be written this way they will not end. Irrational numbers are numbers like pi, phi, e (Euler's number) and a lot of square roots.


Is the square root of any whole number an integer ar an irrational number?

Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.


Tell whether each number is rational?

Rational numbers include integers, and any number you can write as a fraction (with integers in the numerator and denominator). Most numbers that include roots (square roots, cubic roots, etc.) are irrational - if you take the square root of any integer except a perfect square, for example, you'll get an irrational number. Expressions involving pi and e are also usuallyirrational.


Are uneven square roots rational or irrational why?

They are rational because the characteristic of evenness and unevenness is relevant only in the context of integers. And all integers are rational.


Who can you tell what is rational and irrational?

A rational number is one that can be expressed as the ratio of two integers, for instance, 1/3, -5/3, 8 (which is equal to 8/1). An irrational number can't be expressed as the ratio of two integers. It has been proven that the square root of 2 (as well as the square root of any positive integer that is not a perfect square) is irrational. Pi and e, two important numbers in mathematics, are also irrational. It has also been proven that there are more irrational than rational numbers.


Is the square root of 4.1 a rational or irrational number?

[ square root of (4.1) ] is irrational. But [ square root of (4) ] is rational.


Why an irrational number plus an irrational number equal a rational?

That simply isn't true. The sum of two irrational numbers CAN BE rational, but it can also be irrational. As an example, the square root of 2 plus the square root of 2 is irrational.
