Question

Plz help me !!!!!!!!!!!

Answer 1

Only (-3)(-5) = + 15, so the fourth answer is the correct one.

Answer 2

Answer:
`\bold{d.\ \sqrt[3]{-3}\cdot \sqrt[3]{-5} }`

Explanation:

`a)\ \sqrt[3]{-5}\cdot \sqrt[3]{3} =\sqrt[3]{-15}\\eq \sqrt[3]{15} \\\\b)\ \sqrt[3]{-15}\cdot \sqrt[3]{1} =\sqrt[3]{-15}\\eq \sqrt[3]{15}\\\\c)\ \sqrt[3]{5}\cdot \sqrt[3]{3} =\sqrt[3]{-15}\\eq \sqrt[3]{15}\\\\\large{d)\ \sqrt[3]{-3}\cdot \sqrt[3]{-5} =\sqrt[3]{15}= \sqrt[3]{15} }`
