# Integration help

#### LUmath09

1. The problem statement, all variables and given/known data
Integrate: ∫e^∛x

2. Relevant equations

3. The attempt at a solution
this is my attempt but I keep getting stuck
∫e^∛x u=∛x
du=1/(3x^(2⁄3)0 dx
3x^(2⁄3) du= dx
3∫e^u x^(2⁄3) du

After this step I have tried integration by parts and a second substitution but like I said before I keep getting stuck. Any hints to get me going in the right direction are greatly appreciated.

I suppose I might be able to integrate that if I knew what "∛" meant! I don't know what you see on your reader but I see a little square that indicates a code that does not correspond to a character. How about rewriting your question without any "special codes"?

that "little square + x"= x^(1/3)

once you let u=x^(1/3) and you want no x anymore...Notice that x^(2/3)=u^2 would make the integration nice looking:!!)
