Answer:

C. 4.714*10^9

Step-by-step explanation:

Multiply 31.514*14900000

the answer will be 4714494400

In all of the answers it shows 4.714. notice how the decimal is in between 4 and 7. count the numbers and stop once you're at 7. there are 9 numbers. so it will be 4714494400 to the 9th power. which is 4.714*10^9 .
