Question

(x-y)=(a-b)prove that it is irrational

Answer 1

Answer:

For every value of x belongs to R, x−x+

2

i.e.,

2

is an irrational number.

Therefore, it is reflexive.

Now Let's say x=

2

and y=2 then x−y+

2

=2

2

−2 which is irrational

but when y=

2

and x=2,

x−y+

2

is not irrational;
