Could you maybe make your step-by-step process a little clearer? It's a little difficult for me to follow you.

Also, I assume we're solving for y given y'?

I already got it. Sorry for bothering you guys. My problem was that I forgot to differentiate -theta in 3^(-theta).

The final answer I have is -2*3^(-θ)ln(3)

That ln(3) should be in the denominator I think.
