This document discusses writing very large and very small numbers in standard form for easier use in calculations. It provides examples of rewriting the numbers 4,504,000,000 in standard form as 4.504 x 109 and 0.000 000 000 0667 in standard form as 6.67 x 10-11. It also explains that the escape velocity from each planet, which is calculated using the planet's radius and mass, depends on these values and the gravitational constant.
