What does a negative exponent mean?

A negative exponent means take the reciprocal: x⁻ⁿ = 1/xⁿ. For example, 2⁻³ = 1/2³ = 1/8 = 0.125.

What does a fractional exponent mean?

A fractional exponent represents a root: x^(1/n) = ⁿ√x. For example, 8^(1/3) = ∛8 = 2. And x^(m/n) = (ⁿ√x)^m.

What is 0 raised to the 0?

Mathematically, 0⁰ is often defined as 1, though it can be considered indeterminate in some contexts. Most calculators return 1.

What are the laws of exponents?

Key laws: x^a × x^b = x^(a+b); x^a ÷ x^b = x^(a-b); (x^a)^b = x^(ab); x^0 = 1; x^1 = x.
