व्यंजक \(x^2+x^{-1}+x^0\) बहुपद है या नहीं?
Is \(x^2+x^{-1}+x^0\) a polynomial or not?
Explanation opens after your attempt
Correct Answer
C. नहीं, क्योंकि \(x^{-1}\) की घात ऋणात्मक हैNo, because \(x^{-1}\) has a negative power
Concept
In \(x^{-1}\), the variable has a negative power. One invalid power makes the whole expression not a polynomial.
Why this answer is correct
The correct answer is C. नहीं, क्योंकि \(x^{-1}\) की घात ऋणात्मक है / No, because \(x^{-1}\) has a negative power. In \(x^{-1}\), the variable has a negative power. One invalid power makes the whole expression not a polynomial.
Exam Tip
\(x^{-1}\) में चर की घात ऋणात्मक है। एक अमान्य घात होने से पूरा व्यंजक बहुपद नहीं रहता।
