Answer 1

Resposta:

B) 0,0336

Explicação passo-a-passo:

${(0.2)}^{3} + {(0.16)}^{2}$

0,2³= 0,2×0,2×0,2=0,008

0,16²= 0,16×0,16=0,256

$0.256 + 0.008 = 0.0336$

Answer 2

$\sf \left(0,\:2\right)^3+\left(0,\:16\right)^2\\\\\\0.2^3=0.008\\\\\\=0.008+0.16^2\\\\\\0.16^2=0.0256\\\\\\=0.008+0.0256\\\\\\\to \boxed{\sf =0.0336}$
