differentiation f(x)=xe^(5x), f'(x)=(1/5)
ok so i got 5xe^5x + e^5x
now what do i do with the (1/5).
and is my differentiation correct?

your differentiation is correct. as to what to do with the (1/5), i think you just equate it to the derivative and i guess try to solve for x (which i think will be hard) what were the full instructions?Quote:

i'm confused also.
but i don't know if he means to do the integral of it.
that was all the directions.
like should i do integral of 5e^(5x)x+(e^5x) x dx ?
you're telling me the question was phrased just like that?Quote:
