a)4,1 x 10^6

b)3,9 x 10^3

c)4,1 x 10^3

d)4,1

Answer 1

$\boxed{\boxed{\boxed{\boxed{\mathsf{1,2\times10^3+2,9\times10^3=4,1\times10^3}}}}}$

Answer 2

Oie, Td Bom?!

>>> Resposta: opção C.

$x + y$

$1,2 \times 10 {}^{3} + 2,9 \times 10 {}^{3}$

$(1,2 + 2,9) \times 10 {}^{3}$

$4,1 \times 10 {}^{3}$
