The Power of a Quotient Rule of Exponents
Captions available
The idea
The power of a quotient rule of exponents applies an exponent to numerator and denominator alike: (a/b)ⁿ = aⁿ/bⁿ for nonzero b.
In practice
(3/4)² equals 3²/4², which is 9/16 — both the 3 and the 4 get squared.
Where people slip
Forgetting to raise the denominator inflates the result.
