For a non-zero base \(a\), which rule represents division of powers with the same base?
Answer and explanation
Correct answer: \(a^m \div a^n=a^{m-n}\)
When powers have the same non-zero base, their exponents are subtracted, so \(a^m\div a^n=a^{m-n}\). For example, \(a^5\div a^2=a^3\). Exam tip: addition of exponents is used in multiplication, not division.
