Answer and explanation
Correct answer: \(a^{-n}=\frac{1}{a^n}\), जहाँ \(a\ne0\)
A negative exponent denotes the reciprocal of the corresponding positive power: \(a^{-n}=1/a^n\), provided \(a\ne0\). Option B only changes the sign, so it is incorrect. In exams, always check the non-zero base condition.
