625n16

Explanation:

When you raise a whole expression, xn, to a power, you are effectively multiplying it by itself by n number of times. A common mistake in this process is to add four to the n but this is not correct. You, by raising 5n4 to the fourth power, are doing this:

(5n4)(5n4)(5n4)(5n4)

From here its fairly simple, you just multiply 5 by itself 4 times and n4 by itself 4 times.

From this you should get

54n44=625n16
