कौन-सा व्यंजक (x) में बहुपद नहीं है लेकिन (x) के बिना स्थिर पद भी रखता है?
Which expression is not a polynomial in (x) but also has a constant term?
Explanation opens after your attempt
Correct Answer
C. \(x^{-2}+7\)
Concept
The power in \(x^{-2}\) is negative, so it is not a polynomial. (7) is only a constant term, and the issue is the negative power.
Why this answer is correct
The correct answer is C. \(x^{-2}+7\). The power in \(x^{-2}\) is negative, so it is not a polynomial. (7) is only a constant term, and the issue is the negative power.
Exam Tip
\(x^{-2}\) की घात ऋणात्मक है इसलिए यह बहुपद नहीं है। (7) केवल स्थिर पद है और समस्या ऋणात्मक घात से है।
