[Solved] The difference of two irrational number is ____

The difference of two irrational number is NOT always irrational. Let’s see with example

Example one:

Lets have x and y as irrational numbers
Not to Check : x−y is rational or irrational.
Let x = √2 and y = √2 both are irrational

Now let’s calculate x- y

x-y=√2-√2=0
and 0 is rational.

Another Example

(4+2) and (2+2) are irrational numbers

Lets substract them

(4+√2) – (2+√2) = ?

= 42 +22

=2 {which is rational}

So this proves that difference of two irrational numbers are not always an irrational number

so for the question

The difference of two irrational number is —————- always irrational.​

Answer is FALSE
