What is the value of (9^0)?
Answer and explanation
Correct answer: 1
For any non-zero number, the zero-exponent rule is \(a^0=1\), where \(a\ne0\). Therefore, \(9^0=1\). The value 9 is \(9^1\), not a number raised to the power 0. Exam tip: remember zero exponents using \(a^m/a^m=a^{m-m}=a^0=1\), rather than treating the exponent as multiplication by 0.
