Explanation opens after your attempt
Correct Answer

C. \(\frac{x+4}{x}\)

Step 1

Concept

\(\frac{x+4}{x}=1+\frac{4}{x}\) and \(\frac{4}{x}=4x^{-1}\). Due to the negative power, it is not a polynomial.

Step 2

Why this answer is correct

The correct answer is C. \(\frac{x+4}{x}\). \(\frac{x+4}{x}=1+\frac{4}{x}\) and \(\frac{4}{x}=4x^{-1}\). Due to the negative power, it is not a polynomial.

Step 3

Exam Tip

\(\frac{x+4}{x}=1+\frac{4}{x}\) है और \(\frac{4}{x}=4x^{-1}\) है। ऋणात्मक घात के कारण यह बहुपद नहीं है।
