Why is \(7x^2+x^{-4}+3\) not a polynomial?
Explanation opens after your attempt
C. क्योंकि इसमें \(x^{-4}\) हैBecause it has \(x^{-4}\)
Concept
In \(x^{-4}\), the power of the variable is negative. Negative powers are not accepted in a polynomial.
Why this answer is correct
The correct answer is C. क्योंकि इसमें \(x^{-4}\) है / Because it has \(x^{-4}\). In \(x^{-4}\), the power of the variable is negative. Negative powers are not accepted in a polynomial.
Exam Tip
\(x^{-4}\) में चर की घात ऋणात्मक है। बहुपद में ऋणात्मक घात स्वीकार नहीं होती।
