Explicație pas cu pas:
[tex] \sqrt{ \frac{1}{9} } = \frac{ \sqrt{1} }{ \sqrt{9} } = \frac{1}{3} \\ [/tex]
[tex] \sqrt{ \frac{9}{4} } = \frac{ \sqrt{9} }{ \sqrt{4} } = \frac{3}{2} \\ [/tex]
[tex] \sqrt{ \frac{25}{16} } = \frac{ \sqrt{25} }{ \sqrt{16} } = \frac{5}{4} \\ [/tex]
[tex] \sqrt{ \frac{100}{49} } = \frac{ \sqrt{100} }{ \sqrt{49} } = \frac{10}{7} \\ [/tex]
[tex] \sqrt{0.25} = \sqrt{\frac{25}{100}} = \frac{ \sqrt{25} }{ \sqrt{100} } = \frac{5}{10} = 0.5 \\ [/tex]
[tex] \sqrt{0.81} = \sqrt{ \frac{81}{100} } = \frac{ \sqrt{81} }{ \sqrt{100} } = \frac{9}{10} = 0.9 \\ [/tex]
[tex] \sqrt{1.44} = \sqrt{ \frac{144}{100} } = \frac{ \sqrt{144} }{ \sqrt{100} } = \frac{12}{10} = 1.2 \\ [/tex]
[tex] \sqrt{3.24} = \sqrt{ \frac{324}{100} } = \frac{ \sqrt{324} }{ \sqrt{100} } = \frac{18}{10} =1.8 \\ [/tex]
[tex] \sqrt{5.76} = \sqrt{ \frac{576}{100} } = \frac{ \sqrt{576} }{ \sqrt{100} } = \frac{24}{10} = 2.4 \\ [/tex]
[tex] \sqrt{12.25} = \sqrt{ \frac{1225}{100} } = \frac{ \sqrt{1225} }{ \sqrt{100} } = \frac{35}{10} = 3.5 \\ [/tex]
