Explanation opens after your attempt
Correct Answer
C. क्योंकि \(x^{-1}\) की घात ऋणात्मक हैBecause the power in \(x^{-1}\) is negative
Concept
The power in \(x^{-1}\) is negative. Such a power is not allowed in a polynomial.
Why this answer is correct
The correct answer is C. क्योंकि \(x^{-1}\) की घात ऋणात्मक है / Because the power in \(x^{-1}\) is negative. The power in \(x^{-1}\) is negative. Such a power is not allowed in a polynomial.
