कौन-सा कथन \(x^0+x^{-1}+2\) के बारे में सही है?
Which statement is correct about \(x^0+x^{-1}+2\)?
Explanation opens after your attempt
Correct Answer
C. यह बहुपद नहीं है क्योंकि \(x^{-1}\) हैIt is not a polynomial because it has \(x^{-1}\)
Concept
\(x^0\) is valid but \(x^{-1}\) is not valid. One invalid term prevents the whole expression from being a polynomial.
Why this answer is correct
The correct answer is C. यह बहुपद नहीं है क्योंकि \(x^{-1}\) है / It is not a polynomial because it has \(x^{-1}\). \(x^0\) is valid but \(x^{-1}\) is not valid. One invalid term prevents the whole expression from being a polynomial.
Exam Tip
\(x^0\) मान्य है लेकिन \(x^{-1}\) मान्य नहीं है। एक अमान्य पद पूरे व्यंजक को बहुपद नहीं रहने देता।
