Find two irrational numbers between 0.1 and 0.12.

21 Find two irrational numbers between 2 and 2.5. 22 In the following equations, find which of the variables x, y, z etc. represent rational numbers and which represent irrational numbers:
        (i) x² = 5
        (ii) y² = 9
        (iii) z² = 0.04
        (iv) u² = 
        (v) v² = 3
        (vi) w³ = 27
        (vii) t² = 0.4 24 Give an example to show that the product of a rational number and an irrational number may be a rational number. 25 Give two irrational number lying between 𢆢 and 𢆣.
