Approximating World Population with Powers of 10

The video tutorial explains how to approximate the populations of the United States and the world in 2014 using scientific notation. It demonstrates rounding techniques and compares the populations by dividing the world population by the US population, using exponent rules to simplify the calculation.

What was the approximate population of the United States in 2014?

• 3 times 10^9

• 3 times 10^10

• 3 times 10^8

• 3 times 10^7

If the U.S. population in 2014 was rounded to the nearest hundred million, what would it be?

• 400,000,000

• 200,000,000

• 100,000,000

• 300,000,000

What is the scientific notation for 300,000,000?

• 3 times 10^9

• 3 times 10^8

• 3 times 10^7

• 3 times 10^10

What was the approximate population of the world in 2014?

• 7 times 10^7

• 7 times 10^8

• 7 times 10^9

• 7 times 10^10

If the world population in 2014 was rounded to the nearest billion, what would it be?

• 7,000,000,000

• 9,000,000,000

• 6,000,000,000

• 8,000,000,000

What is the scientific notation for 7,000,000,000?

• 7 times 10^10

• 7 times 10^7

• 7 times 10^9

• 7 times 10^8

How many times larger was the world population compared to the U.S. population in 2014?

• 30 times

• 40 times

• 10 times

• 20 times

What is the result of dividing 10^9 by 10^8?

• 1
