x⁰ = 1

x¹ = x

x^-n = 1/xⁿ

x^n means multiply x by itself n times. 2^5 = 2 × 2 × 2 × 2 × 2 = 32.

Any non-zero number raised to 0 equals 1. x^0 = 1. This is a mathematical convention.

x^(-n) = 1/(x^n). Negative exponents flip the base to the denominator.

x^(1/2) = √x. Fractional exponents represent roots. x^(1/3) = cube root of x.
