Is \(6x^3+\frac{4}{x}\) a polynomial or not?

Explanation opens after your attempt
Correct Answer

B. नहीं, क्योंकि \(\frac{4}{x}\) में चर हर में हैNo, because in \(\frac{4}{x}\) the variable is in the denominator

Step 1

Concept

In \(\frac{4}{x}\), the power of (x) is (-1). Therefore this expression is not a polynomial.

Step 2

Why this answer is correct

The correct answer is B. नहीं, क्योंकि \(\frac{4}{x}\) में चर हर में है / No, because in \(\frac{4}{x}\) the variable is in the denominator. In \(\frac{4}{x}\), the power of (x) is (-1). Therefore this expression is not a polynomial.

Step 3

Exam Tip

\(\frac{4}{x}\) में (x) की घात (-1) है। इसलिए यह व्यंजक बहुपद नहीं है।
