Exponents & Roots

Understanding Exponents & Roots

Exponents are a way to show repeated multiplication. Example:

2³ = 2 × 2 × 2 = 8

Square Roots (√) find a number that, when multiplied by itself, gives another number. Example:

√9 = 3 because 3 × 3 = 9

Cube Roots (³√) find a number that multiplies itself three times to give another number. Example:

³√27 = 3 because 3 × 3 × 3 = 27
