B and C are the only correct answers
Answer:
2,087,000,000 583,000 3,000,000
Step-by-step explanation:
You're taking the decimal point of 2.087 and moving it to the right nine times, getting you 2,087,000,000.
The same applies to 5.83 x 10^5, moving the decimal point to the right five times, getting you 583,000.
3 x 10^6 -> 3,000,000
