व्यंजक \(x^2+\frac{1}{x^3}\) बहुपद क्यों नहीं है?
Why is \(x^2+\frac{1}{x^3}\) not a polynomial?
Explanation opens after your attempt
Correct Answer
B. क्योंकि \(\frac{1}{x^3}=x^{-3}\) हैBecause \(\frac{1}{x^3}=x^{-3}\)
Concept
In \(\frac{1}{x^3}\), the variable has power (-3). Negative powers are not valid in a polynomial.
Why this answer is correct
The correct answer is B. क्योंकि \(\frac{1}{x^3}=x^{-3}\) है / Because \(\frac{1}{x^3}=x^{-3}\). In \(\frac{1}{x^3}\), the variable has power (-3). Negative powers are not valid in a polynomial.
Exam Tip
\(\frac{1}{x^3}\) में चर की घात (-3) है। बहुपद में ऋणात्मक घात मान्य नहीं होती।
