72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
Find the difference between the two numbers, then add an irrational number between zero and one, divided by this difference, to the lower number. Such an irrational number might be pi/10, (square root of 2) / 2, etc.
Irrational numbers are infinitely dense. Between any two numbers, there are infinitely many irrational numbers. So if it was claimed that some irrational, x, was the closest irrational to 6, it is possible to find an infinite number of irrationals between 6 and x. Each one of these infinite number of irrationals would be closer to 6 than x. So the search for the nearest irrational must fail.
There may be many easier and better ways, but here's how I would do it: -- Square the first given irrational number. -- Square the second irrational number. -- Pick a nice ugly complicated decimal between the two squares. -- Take the square root of the number you picked. It's definitely between the two given numbers, and it would be a miracle if it's not irrational.
An irrational number is expressed as a non-repeating decimal that goes on forever. Write out the enough of the decimal expansion of each number to find the first digit where the two numbers disagree. Truncate the larger number at that digit, and the result is a rational number (terminating decimal) that is between the two.
It is proven that between two irrational numbers there's an irrational number. There's no method, you just know you can find the number.
the numbers between 0 and 1 is 0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.10.

Irrational numbers are infinitely dense. That is to say, between any two irrational (or rational) numbers there is an infinite number of irrational numbers. So, for any irrational number close to 6 it is always possible to find another that is closer; and then another that is even closer; and then another that is even closer that that, ...
Any number that can't be expressed as a fraction is irrational

Surds are normally irrational numbers.
Real numbers which cannot be written in (a/b) form are called as irrational numbers like √3, √5,√2 etc. Now, we discuss applications of irrational numbers:1. Use of pi(π) : pi is an irrational number which is use in many purpose in math like:Area of circle = π * r2 where pi (π) = 3.14 and r is a radius.Circumference of circle = π * d where d is a diameter of circle,2. Use of exponential (e): e is an irrational number which is used in many parts of math-.3. Use of cube root: cube root is basically used to find out area and perimeter of cube and cuboids because both have three dimension structures.4. Use of irrational number to find out domain: irrational numbers are use to find out domain of particular function. For instance, domain of a function lies between 2 and 3 then we can represent them as √5. Similarly when domain lie between 1 and 2 then we represent them as √2 and between 3 and 4, we can represent them as √11 etc.So, irrational numbers are used in finding approx value of any real measurement because it is difficult to find out exact value of real measurement. Irrational numbers are calculating non terminating point of function.For more information visit related links.
