$(- \frac{4}{7})^{1}$
$(\frac{2}{3})^{-2}$
$(-\frac{2}{3})^{-1}$
$(\frac{-3}{4})^{-3}$
$(\frac{1}{5}) ^{-1}$
$(-2)^{4}$
$(2,43)^{0}$
$(-0,5)^{0}$
$(1,45)^{1}$
$(-5)^{1}$
$3^{-1}$
$(-3)^{-2}$
$2^{-4}$
por favor preciso disso certinho e as contas inteiras.....Vlw 

Answer 1

$\boxed{(-2)^4.(\frac{3}{4})^3~\to~ \frac{16.27}{64} ~\to~ \frac{675}{10} }$

$\boxed{(- \frac{4}{7} )^1~\to~- \frac{4}{7} }$

$\boxed{( \frac{2}{3} )^{-2}~\to~ \frac{1}{( \frac{3}{2})^2 } ~\to~ \frac{1}{ \frac{9}{4} } ~\to~ \frac{4}{9} }$

$\boxed{(- \frac{2}{3} )^{-1}~\to~ \frac{1}{- \frac{2}{3} } ~\to~- \frac{3}{2} }$

$\boxed{(- \frac{3}{4} )^{-3}~\to~ \frac{1}{(- \frac{3}{4} )^3} ~\to~ \frac{1}{- \frac{27}{64} } ~\to~- \frac{64}{27} }$

$\boxed{ (\frac{1}{5})^{-1}~\to~ \frac{1}{ \frac{1}{5} } ~\to~5}$

$\boxed{(-2)^4~\to~(-2)(-2)(-2)(-2)~\to~16}$

$\boxed{(2,43)^0~\to~1}$

$\boxed{(-0,5)^0~\to~1}$

$\boxed{(1,45)^1~\to~1,45}$

$\boxed{(-5)^1~\to~-5}$

$\boxed{3^{-1}~\to~ \frac{1}{3} }$

$\boxed{(-3)^{-2}~\to~ \frac{1}{(-3)^2} ~\to~ \frac{1}{9} }$

$\boxed{2^{-4}~\to~ \frac{1}{2^4}~\to~ \frac{1}{16} }$
