Lesson 2: Negative exponents (ASL)# Negative exponents (ASL)

Learn how to rewrite expressions with negative exponents as fractions with positive exponents. A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16. Created by Sal Khan.
