If \(a\ne0\), what is the value of \(a^0\)?
Answer and explanation
Correct answer: 1
By the law of exponents, the zero power of any non-zero number is 1: \(a^0=1\), where \(a\ne0\). Therefore, 1 is correct. The options \(a\) and \(-a\) depend on the base, while 0 is not the general value of a zero power. Exam tip: the zero power of every non-zero number is 1.
