Answer 2

Explicație pas cu pas:

$\sqrt{2 \dfrac{7}{9} } = \sqrt{ \dfrac{25}{9} } = \dfrac{5}{3} = 1\dfrac{2}{3}$

$\sqrt{5 \dfrac{19}{25} } = \sqrt{ \dfrac{144}{25} } = \dfrac{12}{5} = 2\dfrac{2}{5}$

$\sqrt{1 \dfrac{32}{49} } = \sqrt{ \dfrac{81}{49} } = \dfrac{9}{7} = 1 \dfrac{2}{7}$

$\sqrt{11 \dfrac{1}{9} } = \sqrt{ \dfrac{100}{9} } = \dfrac{10}{3} = 3 \dfrac{1}{3}$

$\sqrt{7 \dfrac{9}{16} } = \sqrt{ \dfrac{121}{16} } = \dfrac{11}{4} = 2 \dfrac{3}{4}$

$\sqrt{4 \dfrac{25}{36} } = \sqrt{ \dfrac{169}{36} } = \dfrac{13}{6} = 2 \dfrac{1}{6}$

$\sqrt{4 \dfrac{33}{64} } = \sqrt{ \dfrac{289}{64} } = \dfrac{17}{8} = 2 \dfrac{1}{8}$

$\sqrt{20 \dfrac{1}{4} } = \sqrt{ \dfrac{81}{4} } = \dfrac{9}{2} = 4 \dfrac{1}{2}$

$\sqrt{7 \dfrac{21}{25} } = \sqrt{ \dfrac{196}{25} } = \dfrac{14}{5} = 2 \dfrac{4}{5}$

$\sqrt{6 \dfrac{30}{49} } = \sqrt{ \dfrac{324}{49} } = \dfrac{18}{7} = 2 \dfrac{4}{7}$
