[tex] \sqrt{0.16} = \sqrt{ \frac{16}{100} } = \frac{ \sqrt{16} }{ \sqrt{100} } = \frac{4}{10} = 0.4 \\ \sqrt{1.44} = \sqrt{ \frac{144}{100} } = \frac{ \sqrt{144} }{ \sqrt{100} } = \frac{12}{10} = 1.2 \\ \sqrt{0.49} = \sqrt{ \frac{49}{100} } = \frac{ \sqrt{49} }{ \sqrt{100} } = \frac{7}{10} = 0.7 \\ \sqrt{0.09} = \sqrt{ \frac{9}{100} } = \frac{ \sqrt{9} }{ \sqrt{100} } = \frac{3}{10} = 0.3 \\ \sqrt{0.0625 } = \sqrt{ \frac{625}{10.000} } = \frac{ \sqrt{625} }{ \sqrt{10.000} } = \frac{25}{10} = 2.5[/tex]
