Which is a monomial but not a polynomial in (x)?
Explanation opens after your attempt
Correct Answer
A. \(\frac{7}{x^2}\)
Concept
\(\frac{7}{x^2}=7x^{-2}\), so the power is negative. Having one term is not enough to be a polynomial.
Why this answer is correct
The correct answer is A. \(\frac{7}{x^2}\). \(\frac{7}{x^2}=7x^{-2}\), so the power is negative. Having one term is not enough to be a polynomial.
Exam Tip
\(\frac{7}{x^2}=7x^{-2}\) है, इसलिए घात ऋणात्मक है। एक पद होना बहुपद होने के लिए पर्याप्त नहीं है।
