I'll mark the correct answer the Brainiest

Mathematics
1 answer:
Rufina [12.5K]3 years ago
8 0

Answer:

E

Step-by-step explanation:

To find the sum, you most find the answers for both powers of tens. 10^2 is 100, so 4.9*100=490. 10^3 is 1000, so 6.8^1000= 6800. Add them together and you get 7290, which if divided by 1000, you get 7.29. Since 10^3 is 1000, the correct answer isE.
