Match the following Column – I with Column – II: 

	Column – I		Column – II
A)	If $\int \frac{2^x}{\sqrt{1-4^x}}dx=k{\sin }^{-1}\left(f\left(x\right)\right)+C,$ then klog2 is …. Where f(0) = 1	(P)	0
B)	If  $\int \frac{{\left(\sqrt{x}\right)}^5}{{\left(\sqrt{x}\right)}^7+x^6}dx=a\ln \frac{x^k}{x^k+1}+c,$ then 3ak is …..	(Q)	1
C)	If  $\int \frac{x^4+1}{x{(x^2+1)}^2}dx=k\ln \left|x\right|+\frac{m}{1+x^2}+n,$ Where ‘n’ is the constant of integration, then m + k is ……	(R)	2
D)	If  $\int \frac{dx}{5+4\cos x}=k{\tan }^{-1}\left(m\tan \frac{x}{2}\right)+C,$  then k/m – 2	(S)	3
