Question

O valor de (0,2)³+(0,16)² é ?

Answer 1

Vamos lá:
( 0,2)^3 = 0,2 . 0,2 . 0,2 = 0,008

( 0,16)^2 = 0,16 . 0,16 = 0,0256

0.0080 + 0,0256 = 0,0336

Answer 2

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