Find either f(s) or f(t) as indicated t(e^t+e^2t)^2

There's no "s" in your expression, so there's also no "f(x)."

To help you, I need to know that the instructions for this problem are.

Did you want to expand    f(t) = t(e^t + e^(2t)^2?

f(t) = t * e^t  +  e^(2t) + 2e^(3t) + e^(4t)

If this is not what you wanted, then please go back to ensure that you have copied ALL of the problem statement to .
