Hello Mate!

$i) \sqrt{4} = 2(rational \: no.) \\ ii)3 \sqrt{18} = irrationl \\ iii) \sqrt{1.44} = 1.2 = \frac{12}{10} \\ = \frac{6}{5} (rational)$

$iv) \frac{ \sqrt{9} }{27} = \frac{3}{27} = \frac{1}{9} \\ = 0.111.......(rational \: no.) \\ v) \sqrt{64} = 8(rational \: no.) \\ vi) \sqrt{100} = 10(rational \: no.)$

Hope it helps☺!
