Reference Guide
What Exponents Mean
An exponent tells you how many times to multiply a number by itself. The number being multiplied is the base and the small raised number is the exponent (or power).
We say "2 to the fourth power" or "2 raised to 4." Squaring () means multiplying a number by itself once. Cubing () means multiplying three times.
Square and Cube Numbers
Square numbers form a square grid. means a 3 by 3 grid of 9 unit squares. The first few perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
Cube numbers form a 3D block. means 2 layers of a 2 by 2 grid = 8 unit cubes. The first few perfect cubes are 1, 8, 27, 64, 125, 216.
Special Exponents
Any nonzero number raised to 0 equals 1. , .
Any number raised to 1 is just itself. .
A negative exponent means "take the reciprocal." .
Powers of 10
Powers of 10 are especially important because our number system is base 10. The exponent tells you how many zeros to write after the 1.
This connects directly to place value: is the thousands place, is the millions place. Scientific notation uses powers of 10 to write very large or very small numbers compactly.
