Why is (x^{\frac{1}{2}}+9) not a polynomial?

Answer and explanation

Correct answer: Because the variable has a fractional power

In a polynomial in x, every exponent of x must be a non-negative integer: 0, 1, 2, and so on. The expression x^{1/2} has a fractional exponent. Although x^{1/2} can be written as √x, it still does not meet the exponent rule for a polynomial. Adding the constant 9 does not remove this invalid term.

Therefore, option B gives the correct reason. The expression has two terms and addition is allowed in polynomials, so options C and D do not identify a problem. The number 9 is also a valid constant term, so option A is not the reason. The fractional power of the variable is exactly why x^{1/2} + 9 is not a polynomial in x.
