Simplify. (2/5) ^4 ... words to fill in minimum space

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.
