What is rule of ((a^m)^n)
Answer and explanation
Correct answer: \(a^{mn}\)
When a power is raised to another power, the exponents are multiplied: \((a^m)^n=a^{m\times n}=a^{mn}\). Therefore, option A is correct. Option B is incorrect because adding exponents applies to multiplication of powers with the same base, not to a power raised to another power. Exam tip: for “power of a power,” multiply the exponents.
