How can I find any irrational numbers between two rational numbers
-------------
eg, 3 & 4
3^2 = 9
4^2 = 16
----
The square root of any integer between 9 & 16, non-inclusive, is irrational.
eg, sqrt(10), sqrt(11)
========================
That's one way.

Append a non-repeating decimal form to the lower of the two rational numbers.
-----
Example::
Between 2 and 3 the number 2.10110111011110... is
an irrational greater than 2 and less than 3.

How can I find any irrational numbers between two rational numbers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let "a" and "b" be two rational numbers, with b > a.

Let c = b - a is their difference.

Consider the irrational number sqrt%282%29 and take small part of it, %281%2Fn%29%2Asqrt%282%29, with an integer "n", so small, that sqrt%282%29%2Fn%29 is less than (b-a).

Now consider the number a+%2B+sqrt%282%29%2Fn.

It is 

1. between "a" and "b", and 

2. it is irrational.


It gives the answer to your question.
