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

$2^{Sin(PiX)}$

2. Relevant equations

3. The attempt at a solution

= $e^{(Sin(\PiX})ln2$

y'= $e^{(Sin(\PiX})ln2$ d/dx [Sin $\Pi$X] ln 2

and I'm stuck.... The product rule will automatically lead to to differentiating ln 2.

$\ln 2$ is just a constant. Just leave it there and differentiate the sine. You can simplify that exponential back to its other form in the answer.

I'm an idiot.... Thanks that solved my problem :).
