You can put this solution on YOUR website!
(625n^4)^-1/4
----
Note:
The negative in the exponent means "invert"
The 4 in the denominator means "take the 4th root".
You may perform these operations in either order.
-----------------------------
Apply the root instruction you get:
= (5n)^-1
--
Apply the invert instruction you get:
= 1/(5n)
