# Exponential Derivative problem

Painguy

dy/dθ =2·3^(−θ)

## The Attempt at a Solution

2*(d/dθ)(3^(-θ)
2(3^(-θ)ln(3))
(2ln(3))/(3^θ)

I keep getting this wrong and I'm not sure why. Could someone point out my mistake?

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.
