Which is a monomial but not a polynomial?

Answer and explanation

Correct answer: \(\frac{3}{x}\)

\(\frac{3}{x}=3x^{-1}\) has only one algebraic term, but the exponent of \(x\) is \(-1\). A polynomial cannot have a negative exponent of a variable, so it is not a polynomial. In contrast, \(3x\), \(x^2\), and \(5\) have exponents \(1\), \(2\), and \(0\), respectively, so they are polynomials. Exam tip: Rewrite a variable in the denominator using a negative exponent before checking whether an expression is a polynomial.
