What's the primitive function of f(x)= (3x+2)^5 ?
I thought it was: F(x)= (1/6)*(3x+2)^6
But that's not correct.

Math is for fags, Physics on the other hand is for winners!

f(x)=(3x+2)(3x+2)(3x+2)(3x+2)(3x+2)
f(x)=(9x^2+6x+4)(9x^2+6x+4)(3x+2)
f(x)=(91x^4+54x^3+36x^2 + 54x^3+36x^2+24x + 36x^2+24x+16)(3x+2)
f(x)=(91x^4 + 108x^3 + 108 x^2 +48x + 16)(3x+2)
f(x)=(273x^5+324x^4+324x^3+144x^2+48x + 182x^4+216x^3+216x^2+96x+32)
f(x)=273x^5 + 506x^4 + 540x^3 + 360x^2 + 144x + 32

I think you mean chemistry.

hmmm if its not that the only other things that comes to my mind is that they are asking you for the one where you replace the x for an 1

They want a primitive function, the answer should be F(x)= (1/18)*(3x+2)^6
BUT WHY?!

You got one 6
And then do 3x2 you get 6
And then do 18:2 you get 6
holy shit

It's the same right? But do you know why it has to be that answer?
