What is the standard form for this? 3,500,000,000
- A.
3.5*10^9
- B.
3*10^9
- C.
3.5*10^8
Correct Answer
A. 3.5*10^9Explanation
The standard form for 3,500,000,000 is 3.5*10^9. This is because in standard form, a number is expressed as a decimal number between 1 and 10, multiplied by a power of 10. In this case, 3.5 is the decimal number and 10^9 represents the power of 10, indicating that the number should be multiplied by 10 nine times. Therefore, 3.5*10^9 is the correct standard form for 3,500,000,000.Rate this question:
