Answer:
The population of Oregon in scientific notation is 4×[tex]10^{6}[/tex]
Step-by-step explanation:
* Lets explain the scientific notation
- Scientific notation is the way to write very large numbers or very small
numbers
- Ex: instead of writing 0.0000000056, we write 5.6 × 10^(-9)
Instead of writing 450000000, we write 4.5 × 10^(8)
* Lets solve the problem
- The population of the United States is about 3.2 × 10^8
- the population of the United States is about 80 times the population
of Oregon
- That means population of United States = 80 × population of Oregon
∵ Population of United States = 3.2 × 10^8
∴ 3.2 × 10^8 = 80 × population of Oregon
- Divide both sides by 80
∴ 4000000 = population of Oregon
- Lets write the number in scientific notation
∵ There are six zero
∴ 4000000 = 4 × [tex]10^{6}[/tex]
∴ The population of Oregon in scientific notation is 4×[tex]10^{6}[/tex]
