Answer 1

To express 671,000,000 in scientific notation, you need to move the decimal point so that there's only one non-zero digit to the left of the decimal.

671,000,000 can be rewritten as 6.71 when you move the decimal point to the left 8 places (since there are 8 digits to the right of the first digit).

Thus, 671,000,000 in scientific notation is:

6.71 × 10^8

So the correct answer is:

6.71 × 10^8
