1. The problem statement, all variables and given/known data

$$((e^t)^2)(dy/dt) + (e^t)^2 (t)(y) = t^3((e^t)^2)$$

3. The attempt at a solution

Im suppost to figure out how to rewrite the left side of this equation so when you take the derivative of it, it becomes the current left side of the equation as you see it now. we are doing this so we can solve initial value problems however i am stuck. I know the product rule is involved but it was so long ago that i dont remember it.

Is this right? e^(2t) seems to be common.
