Frequently asked questions
What does a negative exponent mean?
A negative exponent means the reciprocal of the positive power. For example, 2⁻³ = 1 ÷ 2³ = 1/8 = 0.125.
What is a fractional exponent?
A fractional exponent represents a root. For instance, x^(1/2) is the square root of x, and x^(1/3) is the cube root. So 27^(1/3) = 3.
