I'm having some problems with this following min/max problem.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]C= 0.25t{e^-^0^.^3^t}[/tex]

I am being asked to find the Maximum and when it occurs (t)

Using the PR I obtained:

[tex]0.25t . {-0.3{e^-^0^.^3^t} + {e^-^0^.^3^t} . 0.25 [/tex]

Later by factoring

[tex]0.25 . e^-^0^.^3^t[(t - 0.3)][/tex]

Now because SP/TP at dy/dx = 0

I find one to give 0.3, but am not sure what to do with the other one [tex]0.25 . e^-^0^.^3^t[/tex]

When I make it equal to zero I get an answer which is wrong, I'm guessing the error is either in my factorising or transposing the above problem?
