What are the forms of irrational numbers?

Question

i tried searching it. but i couldn't find what i was looking for. :|

Answer 1

Form 1 - Known constants
Pi, Phi, and e are known irrational constants

Form 2
Square root of a non perfect square
Sqrt(5), Sqrt (21) , and Sqrt(3) are examples of irrational numbers

Any number than cannot be written as the ratio of two integers

Answer 2

Hey there!

Rational numbers are in the form a/b, since the numbers either terminate, or has a repeating digits, when it is in a decimal form.

Example.

1/2, 2/3, 1/4 and 5/6.

Irrational numbers have no form, since they can not be expressed in the form a/b. Irrational numbers are numbers that neither terminate nor repeat.

Example.

pi, sqrt(2), e, sqrt(10)

Hope it helps!

Answer 3

Irrational numbers do not have the form of a/b where and b are integers with b<> 0.

Examples of irrational numbers are pi, e, sqrt(2) ,sqrt(3), etc.

Answer 4

There is no certain "form". In fact, an irrational number is one that cannot be represented in a certain form.

As long as it's not rational, it's irrational. So as long as it cannot be represented as the quotient of two integers, you can call it irrational (of course assuming it's not complex!).

Examples:
5 is rational (also an integer) - quotient of integers 5 and 1
2/3 is rational - quotient of the integers 2 and 3
π is irrational - currently it has been calculated to millions of digits past the decimal. It is an infinite decimal.
2i is complex - this should be obvious!

Answer 5

An irrational number is defined as a number that cannot be expressed as a over b (so basically you can't put it in fraction form)

Answer 6

what do you mean forms of irrational numbers?
pi, e, any decimal that does not have a repeating or terminating pattern
