(3/4)
^2
+ (1/3)^-3
.(5/9) obtêm-se

Answer 1

$( \frac{3}{4} )^{2} + ( \frac{1}{3} )^{-3} . ( \frac{5}{9} )$

$(\frac{9}{16} ) + ( \frac{3}{1} ) ^{3} . ( \frac{5}{9} )$

$( \frac{9}{16} ) + ( \frac{27}{1}) . (\frac{5}{9})$

$\frac{9}{16} + \frac{135}{9}$

$\frac{81}{144} + \frac{2160}{144} = \frac{2241} {144} = \frac{249}{16} ou 15,5625$
