Answer:
The required answer is [tex]3 \sqrt[3]{3}[/tex].
Step-by-step explanation:
Consider the provided information.
We need to find the cube root of the expression [tex]\sqrt[3]{81}[/tex].
[tex]\sqrt[3]{81}=\sqrt[3]{27\times 3}[/tex]
Use the property: [tex]\sqrt[n]{ab} =\sqrt[n]{a}\times \sqrt[n]{b}[/tex]
[tex]\sqrt[3]{81}=\sqrt[3]{27}\times \sqrt[3]{3}[/tex]
[tex]\sqrt[3]{81}=3 \sqrt[3]{3}[/tex]
Hence, the required answer is [tex]3 \sqrt[3]{3}[/tex].
