Learning Goal
Part of: Work with radicals and integer exponents — 3 of 4 cluster items
Use numbers expressed in scientific notation to estimate very large or very small quantities
**8.EE.A.3**: Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. *For example, estimate the population of the United States as 3 x 10^8 and the population of the world as 7 x 10^9, and determine that the world population is more than 20 times larger.*

8.EE.A.3: Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 x 10^8 and the population of the world as 7 x 10^9, and determine that the world population is more than 20 times larger.
What you'll learn
- Express very large and very small numbers in scientific notation of the form a x 10^n, where 1 <= a < 10 and n is an integer
- Convert fluently between standard form and scientific notation for numbers spanning magnitudes from 10^-9 to 10^12
- Estimate real-world quantities by rounding to a single digit times an integer power of 10 (e.g., the population of the United States as 3 x 10^8)
- Determine how many times as much one quantity is than another by dividing two numbers expressed in scientific notation and interpreting the result
- Apply scientific notation estimation and comparison to solve real-world problems involving populations, distances, sizes, and other quantities that span extreme scales
