[tex] \sqrt{4 \frac{25}{36} } = \sqrt{ \frac{169}{36} } = \frac{13}{6} = 2 \frac{1}{6} [/tex]
Odp. C
2.
[tex] \sqrt[3]{2 \frac{7}{9} } \div \sqrt[3]{ \frac{3}{5} } = \sqrt[3]{ \frac{25}{9} } \div \sqrt[3]{ \frac{3}{5} } = [/tex]
[tex] = \sqrt[3]{ \frac{25}{9} \times \frac{5}{3} } = \sqrt[3]{ \frac{125}{27} } = \frac{5}{3} [/tex]
5/3=1,667≈2
Odp. B: 2

[tex]4 \sqrt{12} = 4 \sqrt{4 \times 3} = 4 \times 2 \sqrt{3} = 8 \sqrt{3} [/tex]
Odp. C
4.
[tex] \sqrt{99} = \sqrt{9 \times 11} = 3 \sqrt{11} = 3 \times 3.317[/tex]
