b)3.10^3 + 4.10^3
c)5.10^4 + 8.10^5
d)7.10^2 - 5.10^3
e)6.10^4 - 4.10^2
f)3.10^3 - 2.10^3​

Answer 1

Resposta:

A) 3.100+4.100= 300+400 = 700

B) 3.1000+4.1000= 3000.4000 = 7000

C) 5.10000+8.100000= 50000+800000= 850000

D) 7.100-5.1000= 700-5000= 4300

E) 6.10000-4.100= 60000-400= 59600

F) 3.1000-2.1000= 3000-2000= 1000
