Answer:
3
Step-by-step explanation:
Given
[tex]\sqrt[3]{\sqrt{729} }[/tex]
Evaluate from the ' inside- out ' , that is
[tex]\sqrt{729}[/tex] = 27 , then
[tex]\sqrt[3]{27}[/tex]
= 3
[tex] \sqrt[3]{ \sqrt{729} } [/tex]
[tex] = \sqrt[3]{ \sqrt{ {27}^{2} } } [/tex]
[tex] = \sqrt[3]{27} [/tex]
[tex] = \sqrt[3]{ {3}^{3} } [/tex]
[tex] = 3[/tex] ✅
