24ya really very easy
(1+x)^n=C_0+c_1x+C_2x^2+....
inegrating wrt x, limits 0 to 2
\int_{0}^{2}(1+x)^n=\int_{0}^{2}[C_0+c_1x+C_2x^2+....]
u will get teh ans

1@eureka.
what about the binomial coefficients.
in your expression they are nCr
but in the question something totally different.
maybe something in hidden layers i cannot see. so just elaborate a bit in that case ?.
24@ philip....
how can index of expansion change ????
teh coeff in ques are 2.C01+ 22.C12+..
and not 2C01+ 22C12+..

1No dude, its its the latter case!!
I think I had it written clearly.[7]
1But that is the question...
(or there must be a misprint??)
1I can't prove you wrong. I found fault in my solution[2][4]
24surely misprint.....
but u said u have proved it..tell me how u did taht [6]
1Bhai eureka, I said that I found fault in my solution...u want the wrong proof?? I can give you that...
But not here(Apni public insult nahi karani!!!)[14]
24kkkkkkkkk
no prob dude.....maybe ididnt get ur point....
anyways ur prob solved now.thats the best thing[1]
12, 22, 23, ..... etc. are not the index (n)..but they r the co-efficients of C0, C1,, C2,..etc....
