​

Answer 1

Answer:

difference is a rational number

Answer 2

Answer:

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+

and b=2+

and we now calculate a−b as follows
