State
A rational exponent of m/n means the nth root raised to the mth power: a^(m/n) = (ⁿ√a)ᵐ.
Show
16^(3/4) takes ⁴√16 = 2, then cubes it: 2³ = 8. Root first keeps the numbers small.
Watch for
The denominator is the root; the numerator is the power.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
