Formula

x n = x × x × … × x ( n times )
Zero exponent: x0 = 1 (for x ≠ 0)
Negative exponent: x−n = 1 / xn
Fractional exponent: x1/n = n√x
General fractional: xa/b = b√(xa)
x
Base — the number being raised to a power.
n
Exponent — how many times the base is multiplied (or which root for fractions).
