4+  2 and 2+  2

Step-by-step explanation:

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator and the denominator are whole numbers.  

On the other hand, all numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.

So, let us take two irrational numbers a=4+  2  and b=2+ 2  and we now calculate a−b as follows:  a−b=(4+  2  )−(2+  2)=4+  2 −2−  2 =2=  1 2

​  

Therefore, the difference of two irrational numbers a and b is 2 and from the above defination of rational numbers, we get that 2 is a rational number.

Hence, the difference of two irrational numbers 4+  2 and 2+  2  is a rational number.
