कौन-सा व्यंजक (u) में बहुपद है लेकिन (x) में बहुपद नहीं माना जाएगा यदि (x) हर में हो?

Which expression is a polynomial in (u) but not considered a polynomial in (x) if (x) is in the denominator?

Explanation opens after your attempt
Correct Answer

B. \(u^2+\frac{1}{x}\)

Step 1

Concept

With respect to (u), \(\frac{1}{x}\) is like a constant, so it is a polynomial in (u). With respect to (x), \(\frac{1}{x}\) has power (-1).

Step 2

Why this answer is correct

The correct answer is B. \(u^2+\frac{1}{x}\). With respect to (u), \(\frac{1}{x}\) is like a constant, so it is a polynomial in (u). With respect to (x), \(\frac{1}{x}\) has power (-1).

Step 3

Exam Tip

(u) के संदर्भ में \(\frac{1}{x}\) स्थिर जैसा है, इसलिए यह (u) में बहुपद है। लेकिन (x) के संदर्भ में \(\frac{1}{x}\) की घात (-1) है।
