Witam.
[tex]a) \: \sqrt{12} \ = \sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2 \sqrt{3} [/tex]
[tex]b) \: \sqrt{20} = \sqrt{4 \times 5} = \sqrt{4} \times \sqrt{5} = 2 \sqrt{5} [/tex]
[tex]c) \: \sqrt{50} = \sqrt{25 \times 2} = \sqrt{25} \times \sqrt{2} = 5\sqrt{2} [/tex]
[tex]d) \: \sqrt{180} = \sqrt{36 \times 5} = \sqrt{36} \times \sqrt{5} = 6 \sqrt{5} [/tex]
[tex]e) \: \sqrt[3]{16} = \sqrt[3]{8 \times 2} = \sqrt[3]{8} \times \sqrt[3]{2} = 2 \sqrt[3]{2} [/tex]
[tex]f) \: \sqrt[3]{2000} = \sqrt[3]{1000 \times 2} = \sqrt[3]{1000} \times \sqrt[3]{2} = 10 \sqrt[3]{2} [/tex]
