a
[tex] \sqrt[3]{5} \times \sqrt[3]{25} = \sqrt[3]{5 \times 25} = \sqrt[3]{5 \times {5}^{2} } = \sqrt[3]{? {5}^{3} } = 5[/tex]
b
[tex] \sqrt[3]{7} \times \sqrt[3]{49} = \sqrt[3]{7 \times 49} = \sqrt[3]{7 \times {7}^{2} } = \sqrt[3]{ {7}^{3} } = 7[/tex]
c
[tex] \sqrt[3]{25} \times \sqrt[3]{40} = \sqrt[3]{25 \times 40} = \sqrt[3]{1000} = \sqrt[3]{ {10}^{3} } = 10[/tex]
d
[tex] \frac{ \sqrt[3]{?16} }{ \sqrt[3]{2} } = \sqrt[3]{ \frac{16}{2} } = \sqrt[3]{8} = \sqrt[3]{ {2}^{3} } = 2[/tex]
e
[tex] \frac{ \sqrt[3]{81} }{ \sqrt[3]{3} } = \sqrt[3]{ \frac{81}{3} } = \sqrt[3]{27} = \sqrt[3]{ {3}^{3} } = 3[/tex]
f
[tex] \sqrt[3]{40} \div \sqrt[3]{5} = \sqrt[3]{ \frac{40}{5} } \sqrt[3]{8} = \sqrt[3]{ {2}^{3} } = 2[/tex]
