Answer 1

Propriedade do radical aritmético

$\boxed{ \boxed{\boxed{\displaystyle\mathsf{\sqrt[n]{\sqrt[m]{a}}=\sqrt[n\cdot\,m]{a}}}}}$

$\boxed{\boxed{\boxed{\mathsf{\sqrt[n]{a^m}=\sqrt[n\div\,p]{a^{m\div\,p}}}}}}$

$\dotfill$

$\mathsf{\sqrt{\sqrt{64}}=\sqrt[2\cdot\,2]{64}=\sqrt[4]{64}}\\\mathsf{\sqrt[4]{2^6}=\sqrt[4\div2]{2^{6\div2}}}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{\sqrt{2^3}=\sqrt{2^2\cdot\,2}=2\sqrt{2}}}}}}$
