If \(m\ne0\) and \(n\ne0\), what is the value of \(m^0+n^0\)?

Answer and explanation

Correct answer: 2

The zero power of every non-zero number is 1. Thus, \(m^0=1\) and \(n^0=1\), so \(m^0+n^0=1+1=2\). The option \(m+n\) is incorrect because the base does not remain in the result when its exponent is zero. Exam tip: remember that \(a^0=1\) for \(a\ne0\).
