What is the value of (1/2)⁻³?

Answer: 8

A negative exponent inverts the base: (1/2)⁻³ = 2³ = 8.

Common wrong answers

If you answered 1/8
1/8 is (1/2)³, ignoring the negative sign.
If you answered -8
−8 treats the negative exponent as a negative sign.
If you answered -1/8
−1/8 both ignores the inversion and adds a sign.
