Chapter 5 - Section 5.1 - Exponents and Scientific Notation - Exercise Set: 129


$.0095$ square kilometers

Work Step by Step

We are given that Chiricahua National Monument contains $9.5\times10^{-3}$ square kilometers of privately owned land. Since the exponent is negative, move the decimal 3 places to the left. Note that 3 places to the left will be 2 decimal places past the first digit (9), so we will add 2 zeroes before 9. $9.5\times10^{-3}=.0095$ square kilometers
