One billion is equal to 10 to the power of how many?

Explanation:
Understanding powers of ten and place value helps. A billion is 1 followed by nine zeros, which is 10^9. In the short-scale system commonly used today, 10^3 is a thousand, 10^6 is a million, and 10^9 is a billion. So 10 to the power of nine equals 1,000,000,000. The other options would be 10^8 (100,000,000), 10^10 (10,000,000,000), and 10^11 (100,000,000,000), which are not one billion.
