In February 2010, the population of the world was approximately 6,800,000,000 people.

Another way of writing this number is:

A. \(6.8 \times 10^8\)

B. \(6.8 \times 10^9\)

C. \(68 \times 10^9\)

D. \(68 \times 10^{10}\)

The correct choice is 'B'. The correct exponent is +9. In order to change 6.8 into 6,800,000,000 you have to move the decimal point 9 places in the LARGER direction.

The population of the world in February 2010 can be expressed in scientific notation as 6.8 × 1 0 9 . This is because we move the decimal point 9 places to the right from 6.8 to reach 6,800,000,000. Thus, the correct answer is option B.
