    Answer:

    (i)2 – √5

    Here 2 is a rational number and √5 is a irrational number

    And difference of rational and irrational is always a irrational number

    So that 2 – √5 is a irrational number

    (ii) (3 +  √23) – √23

    Solve the bracket we get

    3 +  √23 – √23  = 3

    and 3 is a rational number so that (3 +  √23) – √23 is a rational number

    (iii)   and 2/7 can be written in form of p/q so it a rational number

    (iv) 1/ √2  is an irrational number because 1 is rational and √2 is irrational and product or division of rational with irrational is always irrational

    (v) 2pi   it is an irrational here 2 is rational and pi is a irrational number and product or division of rational with irrational is always irrational
