Give two irrationall number whose difference is an rational number

Answer 1

Answer:

3 and 5

Step-by-step explanation:

Answer 2

Answer:

Two irrational numbers whose difference is an irrational number are:

(√3 + √2) - (√3 - √2)

             AND

(√4 + 3) - (3 -√4)

The answer of the first example is :

(√3 + √9) - (√3 - √9)

= √3 + √2 - √3 + √2

= √3 - √3 + √9 + √9

= 0 + 3 + 3

= 6

(√3 + √2) - (√3 - √2)  = 2 (which is a rational number)

The answer of the second example is :

(√4 + 3) - (3 -√4)

= √4 + 3 - 3 + √4

= √4 + √4 + 3 - 3

= 2 + 2 + 0

= 4

(√4 + 3) - (3 -√4) = 4 (which is a rational number)
