The Quotient Rule of Exponents
Captions available
The idea
The quotient rule of exponents states that dividing powers of the same base subtracts the exponents: aᵐ / aⁿ = aᵐ⁻ⁿ for nonzero a.
In practice
5⁷ / 5⁴ cancels four factors of 5 and leaves 5³ = 125.
Where people slip
Subtract top minus bottom, in that order.
