a) √elevado ao cubo dentro de uma raiz de 64=
b) √√81=

Answer 1

6)

a)

$\blue{3\sqrt{\orange{\sqrt{64}}}}=3\sqrt{\orange{8}}\\ \\ 3×2\sqrt{2}\\ \\ \green{6\sqrt{2}}\\------------- \\\green{\sqrt{ {64}^{3} } } = \sqrt{64 \times 64 \times 64} = \\ \\ \sqrt{64} \times \sqrt{64} \times \sqrt{64} = \\ \\ 8 \times 8 \times 8 = \\ \\ \green{512}$

b)

$\sqrt{ \sqrt{81} } = \\ \\ \sqrt[2×2]{81} = \\ \\\sqrt[4]{81}\\ \\ \green{3}$
