Explanation opens after your attempt
Correct Answer
B. क्योंकि (x^{1 / 2}) की घात पूर्णांक नहीं है / Because the power in \(x^{1 / 2}\) is not an integer
Step 1
Concept
In a polynomial, powers of the variable must be integers. \(x^{1/2}\) has power \(\frac{1}{2}\), so it is not a polynomial.
Step 2
Why this answer is correct
The correct answer is B. क्योंकि \(x^{1 / 2}\) की घात पूर्णांक नहीं है / Because the power in \(x^{1 / 2}\) is not an integer. In a polynomial, powers of the variable must be integers. \(x^{1/2}\) has power \(\frac{1}{2}\), so it is not a polynomial.
