Question

integrate (x(36x^2+35)^(14)dx) if x>0

Answer 1

let u = (36x^2 + 35) --> du = 72x dx

do you know how to substitute them?

Answer 2

yes
36/7du=14dx

Answer 3

you want to substitute them to turn the integral f(x)dx to the form udu

Answer 4

x dx = du/72

Answer 5

ni got as my answer (36x^2+5)^15/1080

Answer 6

but its saying its wrong --- i did it on my calculator

Answer 7

seems right [+ C]

Answer 8

yeah i also addded plus c

Answer 9

it says this when i put in the answer " Can't solve for adaptive parameters"

Answer 10

did you write + 35 or + 5 like you wrote just now?

Answer 11

+35

Answer 12

maybe the answer is infinity, having to do with the x > 0 part, but that would be weird.

the integration is right though
