In (9x^0+4x), (x^0) is considered equal to what?

Answer and explanation

Correct answer: 1

For any non-zero number or variable, the zero-exponent rule is \(x^0=1\), where \(x\ne0\). Therefore, \(9x^0=9\times1=9\), and the expression becomes \(9+4x\). The number 9 is the coefficient of \(x^0\), not the value of \(x^0\). Exam tip: When you see exponent 0, first ensure that the base is non-zero, then replace that power by 1.
