क्या \(2x^2+\frac{3}{x}+1\) (x) में बहुपद है?
Is \(2x^2+\frac{3}{x}+1\) a polynomial in (x)?
Explanation opens after your attempt
B. नहीं क्योंकि इसमें \(\frac{3}{x}\) हैNo because it has \(\frac{3}{x}\)
Concept
\(\frac{3}{x}\) means \(3x^{-1}\), which is not allowed in a polynomial. Powers of the variable must be whole numbers.
Why this answer is correct
The correct answer is B. नहीं क्योंकि इसमें \(\frac{3}{x}\) है / No because it has \(\frac{3}{x}\). \(\frac{3}{x}\) means \(3x^{-1}\), which is not allowed in a polynomial. Powers of the variable must be whole numbers.
Exam Tip
\(\frac{3}{x}\) का अर्थ \(3x^{-1}\) है जो बहुपद में मान्य नहीं है। बहुपद में चर की घातें पूर्ण संख्याएँ होनी चाहिए।
