i)\(\sqrt{23}\)

ii)\(\sqrt{225}\)

iii) 0.3796

iv)sqrt7.478478.....

v)1.101001000100001.....

i)\(\sqrt{23}\)

ii)\(\sqrt{225}\)

iii) 0.3796

iv)sqrt7.478478.....

v)1.101001000100001.....

i) Irrational (Since, it is not a perfect square).

ii)Rational (Since, it is a perfect square).

iii)0.3796 = Rational (terminating)

iv) 7.478478… = Rational (non-terminating repeating.)

v)1.101001000100001… = Irrational (non-terminating non-repeating.)
