Integral(e ^ (x/4) dx)
let u = x/4, du = dx / 4, dx = 4 du
Integral(e ^ (x/4) dx) = 4 Integral(e ^ u du) = 4e^u + C = 4e^(x/4) + C

For a linear function u(x) = px + q
integral e^u(x) dx = [1/u'(x)].e^u(x) + c
where c is an arbitrary constant of integration. In this case integral e^(x/4) dx = 4e^(x/4) + c
to assure yourself differentiate the answer 4.e^(x/4) + c
then you will have e^(x/4).

easy the integate of e^u is e^u /(du/dx )
u= 4x so du/dx = 4
and the integral is (e^4x)/4

â«e^(x/4) dx =
u = x/4
du = dx/4
4du = dx
=>
â«e^(x/4) dx = 4â«e^u du = 4e^u + c
=>
â«e^(x/4) dx = 4e^(x/4) + c

int(e^ax dx) = e^ax / a + c
Luiz S answer is so wrong it's amazing.
