कौन-सा व्यंजक \(\sqrt{x}\) के कारण बहुपद नहीं है?

Which expression is not a polynomial because of \(\sqrt{x}\)?

Explanation opens after your attempt
Correct Answer

C. \(\sqrt{x}+2x\)

Step 1

Concept

\(\sqrt{x}=x^{1/2}\), and \(\frac{1}{2}\) is not an integer power. Hence it is not a polynomial.

Step 2

Why this answer is correct

The correct answer is C. \(\sqrt{x}+2x\). \(\sqrt{x}=x^{1/2}\), and \(\frac{1}{2}\) is not an integer power. Hence it is not a polynomial.

Step 3

Exam Tip

\(\sqrt{x}=x^{1/2}\) होता है और \(\frac{1}{2}\) पूर्णांक घात नहीं है। इसलिए यह बहुपद नहीं है।
