JEE Mains · Maths · STD 12 - 6. Application of derivatives

\(\left( tx ^{\frac{1}{5}}+\frac{(1- x )^{\frac{1}{10}}}{ t }\right)^{10}\) ; જ્યાં\(x \in(0,1)\) ના વિસ્તરણમાં \(‘t'\) થી સ્વતંત્ર પદની મહત્તમ કિંમત ........... છે.

  1. A \(\frac{10 !}{\sqrt{3}(5 !)^{2}}\)
  2. B \(\frac{2.10 !}{3 \sqrt{3}(5 !)^{2}}\)
  3. C \(\frac{2.10 !}{3(5 !)^{2}}\)
  4. D \(\frac{10 !}{3(5 !)^{2}}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\frac{2.10 !}{3 \sqrt{3}(5 !)^{2}}\)

Step-by-step Solution

Detailed explanation

Term independent of \(t\) will be the middle term due to exect same magnitude but opposite sign powers of t in the binomial expression given So \(T _{6}={ }^{10} C _{5}\left( tx ^{2} 5\right)^{5}\left(\frac{(1- x )^{\frac{1}{10}}}{ t }\right)^{5}\)…
