To write 671,000,000 in scientific notation, you need to express it in the form \( a \times 10^n \), where \( a \) is a number between 1 and 10, and \( n \) is an integer.
671,000,000 can be rewritten as:
\[ 6.71 \times 100,000,000 \]
Since \( 100,000,000 \) is \( 10^8 \), we can write:
\[ 671,000,000 = 6.71 \times 10^8 \]
Therefore, the correct answer is:
• 6.71 × 10^8
671,000,000 can be rewritten as:
