\(x^3+x^{2/5}+1\) बहुपद क्यों नहीं है?
Why is \(x^3+x^{2/5}+1\) not a polynomial?
Explanation opens after your attempt
Correct Answer
C. क्योंकि (x^{25}) की घात पूर्णांक नहीं है / Because the power in \(x^{2 / 5}\) is not an integer
Concept
In a polynomial, powers of the variable must be integers. The power in \(x^{2/5}\) is \(\frac{2}{5}\), which is not an integer.
Why this answer is correct
The correct answer is C. क्योंकि \(x^{2 / 5}\) की घात पूर्णांक नहीं है / Because the power in \(x^{2 / 5}\) is not an integer. In a polynomial, powers of the variable must be integers. The power in \(x^{2/5}\) is \(\frac{2}{5}\), which is not an integer.
Exam Tip
बहुपद में चर की घातें पूर्णांक होनी चाहिए। \(x^{2/5}\) की घात \(\frac{2}{5}\) है, जो पूर्णांक नहीं है।
