Giving reason in each case, show that each of the following numbers is irrational.

(i) (ii) (iii)

(iv) (v) (vi)

(i)

We cannot simplify

Hence 4 + is an irrational number.

(ii)

=

We can’t simplify

Hence it is an irrational number.

(iii)

We can’t simplify

Hence it is an irrational number.

(iv)

=

We can’t simplify

Hence it is an irrational number.

(v)

We cannot simplify

Hence it is an irrational number.

(vi)

We cannot simplify

Hence it is an irrational number.
