What is (x^2+1 )^ 5 2 x d x equal to?
Options
- A(x^2+1 )^ 7 2 +c
- B2 7 (x^2+1 )^ 7 2 +c
- C1 7 (x^2+1 )^ 7 2 +c
- DNone of the above
Correct answer
C. 1 7 (x^2+1 )^ 7 2 +c
Step-by-step solution
Put x^2+1=t aligned & 2 x=d x=d t & x d x= d t 2 (t)^ 5 / 2 d t 2 (C) & 1 2 t^ 7 / 2 7 / 2 +c= 1 7 (x^2+1 )^ 7 / 2 +c aligned
