[tex] \sqrt{25 \times 16 \times 49} = 5 \times 4\times 7 = 140[/tex]
[tex] \sqrt{2} \times \sqrt{8} = \sqrt{16} = 4[/tex]
[tex] \sqrt{5} \times \sqrt{20} = \sqrt{100} = 10[/tex]
[tex] \frac{ \sqrt{18} }{ \sqrt{2} } = \sqrt{9} = 3[/tex]
[tex] \sqrt{20} = \sqrt{4 \times 5} = 2 \sqrt{5} [/tex]
[tex] \sqrt{72} = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]
[tex] \sqrt{24} = \sqrt{4 \times 6} = 2 \sqrt{6} [/tex]
[tex] \sqrt{125} = \sqrt{5 \times 25} = 5 \sqrt{5} [/tex]
[tex] \sqrt[3]{40} = \sqrt[3]{8 \times 5} = 2 \sqrt[3]{5} [/tex]
[tex] \sqrt[3]{128} = \sqrt[3]{64 \times 2} = 4\sqrt[3]{2} [/tex]
Mam nadzieję, że dobrze :)
[tex] \sqrt[3]{54} = \sqrt[3]{9 \times 6} = 3 \sqrt[3]{6} [/tex]
