कौन-सा व्यंजक बहुपद नहीं है क्योंकि उसमें \(\frac{1}{x^4}\) है?
Which expression is not a polynomial because it contains \(\frac{1}{x^4}\)?
Explanation opens after your attempt
Correct Answer
A. \(x^4+\frac{1}{x^4}\)
Concept
\(\frac{1}{x^4}=x^{-4}\), which is a negative power. Negative powers are not allowed in polynomials.
Why this answer is correct
The correct answer is A. \(x^4+\frac{1}{x^4}\). \(\frac{1}{x^4}=x^{-4}\), which is a negative power. Negative powers are not allowed in polynomials.
Exam Tip
\(\frac{1}{x^4}=x^{-4}\) है, जो ऋणात्मक घात है। बहुपद में ऋणात्मक घातें स्वीकार्य नहीं हैं।
