If \(\int \frac{x^4}{x-2} d x=p x+q x^2+r x^3+s x^4+t \log |x-2|+C\), where \(C\) is an arbitrary constant and \(p, q, r, s, t\) are real numbers, then the correct arrangement of \(p, q, r, s, t\) is

  1. A \(p>q>r>s>t\)
  2. B \(q>r>p>t>s\)
  3. C \(r>t>s>p>q\)
  4. D \(t>p>q>r>s\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(t>p>q>r>s\)

Step-by-step Solution

Detailed explanation

\( \int \frac{x^4}{x-2} d x = \int \left( x^3 + 2x^2 + 4x + 8 + \frac{16}{x-2} \right) d x \) \( = \frac{x^4}{4} + \frac{2x^3}{3} + \frac{4x^2}{2} + 8x + 16 \log |x-2| + C \) \( = \frac{1}{4} x^4 + \frac{2}{3} x^3 + 2x^2 + 8x + 16 \log |x-2| + C \) Comparing with…
