Correct option (a) 2x
A polynomial consists of terms where the variable has only non-negative integer exponents.
Analyzing Each Option:
(a). 2x – The exponent of x is 1, which is a non-negative integer. This is a valid term of a polynomial.
(b). 3/x – This can be rewritten as 3x ⁻¹. Since the exponent is negative, this is not a polynomial term.
(c). x√x – We rewrite √x as x¹/², so:
x√x = x.x¹/² = x ³/² Since the exponent 3/2 is not an integer, this is not a polynomial terms.
(d). √x – since √x = x ¹/², and the exponent 1/2 is not a integer, this is not a polynomial term.
Final Answer: The correct answer is (a) 2x.
