1. COURSE 3 LESSON 7-1
Scientific Notation
Order the planets from least to greatest in size according to these diameters (in km):
Mars  103
Mercury  103
Saturn 1.2  105
Neptune  104
Diameters (km)
103
104
105
First, order the exponents from least to greatest.

2. Scientific Notation (continued) 6.794  103 4.88  103
COURSE 3 LESSON 7-1
Scientific Notation
(continued)
Compare any factors with the same power of 10.
6.794  103
4.88  103
4.88 < 6.794, so 4.88  103 <  103
4.88  103 Mercury
6.794  103 Mars
4.86  104 Neptune
1.2  105 Saturn
Write the numbers from least to greatest.
The order of the planets is Mercury, Mars, Neptune, and Saturn.
