In which of the following expressions has the product rule of exponents been applied correctly?

Answer and explanation
Correct answer: \(a^m \times a^n = a^{m+n}\)
When powers with the same base are multiplied, their exponents are added; hence \(a^m\times a^n=a^{m+n}\). Multiplying exponents to get \(mn\) is incorrect here. Exam tip: check that the bases match first.
