What is the sum of 4.9 * 10^2 and 6.8 * 10^3?

A.

1.17 * 10^3

B.

1.17 * 10^5

C.

1.17 * 10^7

D.

7.29 * 10^2

E.

7.29 * 10^3

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.
