Scientific notation is often used for working with very small or very large numbers. Describe two situations where using scientific notation might be appropriate. 18. Reasoning. How does a number in scientific notation change when you multiply it by 100? 19. Country A has a population of 8.7 × 109. You hear that country B has twice as many people as country A and country C has twice as many people as country B. How many people live in country C?
