Question

como se resolve este exercicio?

Answer 1

$[ (\frac{1}{(2)^{- \frac{2}{3} }})^{3} - (\frac{2^{6}}{2^{4}})^{ \frac{1}{2} } ] - [ \frac{(3)^{ -\frac{3}{2}} }{ \sqrt{3} } - \frac{5^{ \frac{5}{3}} }{ \sqrt[3]{5^{2}} } ]= \\\\ (4 - 2) - ( \frac{1}{9} - 5) = 2 + \frac{44}{9} = \frac{18 + 44}{99} = \frac{62}{9} =\\\\ \boxed{ \frac{31}{3} = 6 \frac{8}{9}}$
