Answer 1

Resposta:

b) 0,0336

Explicação passo-a-passo:

(0,2)³ + (0,16)² =

0,2 x 0,2 x 0,2 + 0,16 x 0,16 =

0,008 + 0,0256 =

0,0336

Answer 2

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