Answer 2

$a) \: \sqrt{3,24} = \frac{ \sqrt{324} }{ \sqrt{100} } = \frac{18}{10} = 1,8.$

$b) \: \sqrt{4,41} = \frac{ \sqrt{441} }{ \sqrt{100} } = \frac{21}{10} = 2,1.$

$c) \: \sqrt{0,16} = \frac{ \sqrt{16} }{ \sqrt{100} } = \frac{4}{10} = 0,4.$

$d) \: \sqrt{6,25} = \frac{ \sqrt{625} }{ \sqrt{100} } = \frac{25}{10} = 2,5.$
