Converting a Number to Scientific Notation
The number 725,000,000 can be written in scientific notation by placing the decimal point after the first non-zero digit and then counting how many places the decimal has moved. This number is written as \( 7.25 \times 10^n \), where \( n \) is the number of places the decimal moved.
For the number 725,000,000, the decimal point moves 8 places to the left to get from 725,000,000.0 to 7.25. Therefore, the number 725,000,000 would be written in scientific notation as:
\[ 7.25 \times 10^8 \]
