• Calcule a 0.2 à potência de 3 e obtenha 0.008.

$\Large\boxed{\sf(0.2)^{ 3 } +(1.2-0.21) \times 10 ^ { 3 } =}$

• Subtraia 0.21 de 1.2 para obter 099.

$\Large\boxed{\sf0.008+0.99\times 10^{3}}$

• Calcule a 10 à potência de 3 e obtenha 100.

$\Large\boxed{\sf0.008+0.99\times 1000 }$

• Multiplique 0.99 e 100 para obter 990.

$\Large\boxed{\sf0.008+990 }$

• Some 0.008 e 990 para obter 990.008.

$\Large\boxed{\sf990{,}008}$
