Please write your answer in standard notation

Answer 1

200,000 times

Explanation:

The population of China is about 1.4 × 10⁹ . And the hometown of Julie has a population of 7,000 people . We need to find out how many times greater is the population of China than Julie's hometown .

By Question :-

`\rm\implies Population_(China)= 1.4* 10^9`

`\rm\implies Population_(Hometown)= 7,000`

Times by which population of China is more:-

• For finding this divide the population of China by population of hometown .

`\rm\implies ( 1.4 * 10^9 )/(7000) \\\\\rm\implies ( 14 * 10^8)/(7* 10^3)\\\\\rm\implies 2* 10^(8-3) \\\\\rm\implies 2* 10^5 \\\\\rm\implies \boxed{\quad \bf 200,000 \quad }`

Therefore the population of China is greater than 200,000 times .
