Why is my code not working??
I tried sample data. Also made my own test cases, but the judge never gives me 100%

Output
All answers should be to 2 decimal places. 

Weird, but if you round to 2 decimal places, it AC's.

Output
All answers should be to 2 decimal places.

^ maybe that's why

my program works fine on eclipse and gives the correct answer every time, but the judge gives me 10/30?

Re-read the announcement -- it's been updated.
All your output is on the same line.

Ok I have the formula to find the X^P but I still get 20/30. What I am I not considering? I took "" 0^<something> "" into account; the output should be '0.00' in that case...

I don't get what am I missing? Is it that the 0.00 should be just 0 or something?

ln doesn't work for negative numbers.
There's no need for a special formula, though.
