कौन-सा व्यंजक बहुपद नहीं है क्योंकि उसमें (x) की घात \(-\frac{1}{2}\) है?
Which expression is not a polynomial because it has power \(-\frac{1}{2}\) of (x)?
Explanation opens after your attempt
Correct Answer
B. (x^{-12}+5)
Concept
\(-\frac{1}{2}\) is neither zero nor a positive integer. So this power is not valid in a polynomial.
Why this answer is correct
The correct answer is B. \(x^{-1 / 2}+5\). \(-\frac{1}{2}\) is neither zero nor a positive integer. So this power is not valid in a polynomial.
Exam Tip
\(-\frac{1}{2}\) न तो शून्य है और न धनात्मक पूर्णांक। इसलिए यह घात बहुपद में मान्य नहीं है।
