[tex]7 \sqrt[3]{7} + \sqrt[3]{56} = 7 \sqrt[3]{7} + \sqrt[3]{8 \times 7} = 7 \sqrt[3]{7} + 2 \sqrt[3]{7} = 9 \sqrt[3]{7} [/tex]
[tex] \sqrt[3]{2000} - \sqrt[3]{250} = \sqrt[3]{2 \times 1000} - \sqrt[3]{2 \times 125} = 10 \sqrt[3]{2} - 5 \sqrt[3]{2} = 5 \sqrt[3]{2} [/tex]
[tex] \sqrt[3]{3000} + \sqrt[3]{24} - \sqrt[3]{81} = \sqrt[3]{3 \times 1000} + \sqrt[3]{3 \times 8} - \sqrt[3]{3 \times 27} = 10 \sqrt[3]{3} + 2 \sqrt[3]{3} - 3 \sqrt[3]{3} = 9 \sqrt[3]{3} [/tex]
[tex] \sqrt[3]{7000} - \sqrt[3]{7} = \sqrt[3]{7 \times 1000} - \sqrt[3]{7} = 10 \sqrt[3]{7} - \sqrt[3]{7} = 9 \sqrt[3]{7} [/tex]
