What this chapter is about
The mass of the Earth is 5,970,000,000,000,000,000,000,000 kg. The distance from the Sun to Saturn is 1,433,500,000,000 m. Reading, writing, comparing, and calculating with such enormously large (or incredibly small) numbers is practically impossible without a compact notation. Exponents (also called powers or indices) provide exactly this — a concise and elegant way to represent repeated multiplication.
