The Product Rule of Exponents
Captions available
The idea
The product rule of exponents states that multiplying powers of the same base adds the exponents: aᵐ · aⁿ = aᵐ⁺ⁿ.
In practice
2³ · 2² stacks five factors of 2, so it equals 2⁵ = 32.
Where people slip
The bases must match; 2³ · 5² adds nothing.
