Alguien sabe? Con desarrollo Porfis doy corazón

Answer 1

Respuesta:

a) $(\frac{6}{7} )^{3} *\frac{6}{7}$

$(\frac{6}{7} )^{3+1}=(\frac{6}{7}) ^{4} = \frac{6^{4} }{7^{4} } =\frac{1296}{2401}$

1296/2401=0.539775

b) $(\frac{2}{5} )^{6} *(\frac{2}{5} )^{3}$

$(\frac{2}{5} )^{6+3} =(\frac{2}{5} )^{9} =\frac{2^{9} }{5^{9} } =\frac{512}{1953125}$

512/1953125=2.62144x10-4

c) $2*(\frac{1}{2} )^{3}$

$2*\frac{1^{3} }{2^{3} } =2^{1-3} *1^{3} =2^{-2} *1=\frac{1}{2^{2} } =\frac{1}{4}$

1/4=0.25

d) $(-\frac{5}{3} )^{3} *(-\frac{3}{5} )^{-2}$

$(-\frac{5}{3} )^{3} *(-\frac{5}{3} )^{2}$

$(-\frac{5}{3} )^{3+2} =(-\frac{5}{3} )^{5}=(-1)^{5} *\frac{5^{5} }{3^{5} } =-\frac{3125}{243}$

-3125/243=-12.8600823
