Why is x + ∛x not a polynomial?

Answer and explanation

Correct answer: Because ∛x = x¹ᐟ³

Option D is correct because the cube-root term has a fractional exponent. Using the exponent form, ∛x = x^(1/3), so the expression is x^1 + x^(1/3). The defining condition for a polynomial is that the exponent of every variable in every term must be a non-negative integer. The exponent 1 in the first term is valid, but 1/3 in the second term is fractional and therefore invalid for a polynomial in x. Addition is entirely normal in a polynomial, and a polynomial may contain two or more terms. The presence of x itself is also not a problem. Thus the decisive issue is neither the number of terms nor the operation of addition; it is the fractional exponent created by the cube root.
