Answer 1

Vamos lá

Fazemos os cálculos:

A)

$\boxed{\begin{array}{lr} \large \sf 3^{2}.(3^{7})^{4}.\sqrt[3]{3^{12} } \\ \\ 3^{2} \large \sf \times3^{28}\times3^{4}\\ \\ \large \sf 3^{2+28+4} \\ \\ \large \sf \to\boxed{\boxed{\sf 3^{34}}} \end{array}}$

B)

$\boxed{\begin{array}{lr} \large \sf 2^{10} \times\dfrac{1}{2^{5} } \times\sqrt[3]{2^{21} } \\ \\ \large \sf 2^{\diagup\!\!\!\!\!10} \times\dfrac{1}{\diagup\!\!\!\!\!2^{5} } \times\sqrt[3]{2^{21} } \\ \\ \large \sf 2^{5}\times2^{7} \\ \\ \large \sf 2^{5+7} \\ \\ \large \sf\to \boxed{\boxed{\sf 2^{12}}} \end{array}}$
