question
the population of the world on july 4, 2010, was more than 6,850,000,000. write the number in scientific notation. use the multiplication symbol provided when entering your answer.
provide your answer below:

Explanation:

Step1: Move the decimal point

The number is \(6850000000\). Move the decimal point to get a number between \(1\) and \(10\). We get \(6.85\).

Step2: Count the number of places the decimal point moved

The decimal point moved \(9\) places to the left.

Step3: Write in scientific notation

In scientific notation, \(a\times10^{n}\), where \(1\leqslant a < 10\) and \(n\) is an integer. Here \(a = 6.85\) and \(n=9\). So the number in scientific notation is \(6.85\times10^{9}\)

Answer:

\(6.85\times10^{9}\)
