When you have a power to a fraction, you simply take it by the top and then by the bottm.
So, split it into two: (2)^4 and (5)^4
Solve: (2)^4=16
(5)^4=625
So the fraction is: 16/625
Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples).
Therefore, that's the answer.
False if y=f(x) then x= inverse of f(x) or f^-1(x)

hmm.. never heard of properties but take a look at this :D
I believe this might be prime numbers and common numbers
