How do you do the following:
Find y' (y prime)
y=(tanx)^(1/x)
I have no clue how to do this problem

I think they want you to find the derivative ( ' ), ie find dy/dx if y=......
I found y'. It is in the second line of your post...
Use the chain rule, then the quotient rule, then the chain rule again...
Just a hint:
tanx^(1/x) = exp(1/x ln tanx) and the exponential chain rule d exp(u)/du * du/dx where u = 1/x ln(tanx)
