Question

(-2/5)×[(2/4)×(-2/3)²+3] Me ajudem por favor a Armar a fração??​

Answer 1

Resposta:

$\frac{-58}{45}$

Explicação passo a passo:

$(\frac{-2}{5})[(\frac{2}{4})(\frac{-2}{3})^2+3]=\\(\frac{-2}{5})[(\frac{2}{4})(\frac{4}{9})+3]=\\(\frac{-2}{5})[\frac{2}{9}+3]=\\(\frac{-2}{5})[\frac{2}{9}+\frac{27}{9}]=\\(\frac{-2}{5})[\frac{29}{9}]=\\\frac{-58}{45}$

OBS:

$(\frac{2}{4})(\frac{4}{9})=\\\frac{8}{36}=\\\frac{8:4}{36:4}=\\\frac{2}{9}$

Bons estudos!
