JEE Mains · Maths · STD 12 - 7.1 indefinite integral

समाकल \(\int \frac{ dx }{( x +4)^{\frac{8}{7}}( x -3)^{\frac{6}{7}}}\) बराबर है : (जहाँ \(C\) एक समाकलन अचर है)

  1. A \(\left(\frac{x-3}{x+4}\right)^{\frac{1}{7}}+C\)
  2. B \(-\left(\frac{x-3}{x+4}\right)^{-\frac{1}{7}}+C\)
  3. C \(\frac{1}{2}\left(\frac{x-3}{x+4}\right)^{\frac{3}{7}}+C\)
  4. D \(-\frac{1}{13}\left(\frac{x-3}{x+4}\right)^{-\frac{13}{7}}+C\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\left(\frac{x-3}{x+4}\right)^{\frac{1}{7}}+C\)

Step-by-step Solution

Detailed explanation

\(\mathrm{I}=\int \frac{\mathrm{dx}}{(\mathrm{x}+4)^{\frac{8}{7}}(\mathrm{x}-3)^{\frac{6}{7}}}\)\(=\int \frac{\mathrm{dx}}{\left(\frac{\mathrm{x}+4}{\mathrm{x}-3}\right)^{\frac{8}{7}}(\mathrm{x}-3)^{2}}\) Let \(\frac{\mathrm{x}+4}{\mathrm{x}-3}=\mathrm{t}\)…
