try to use the property: (a)^m/(b)^n = (a/b)^n.

example: (8a^5)^(1/2)/(2a)^(1/2) = (8a^5/2a)^(1/2)

then, try to simplify the radicands, (expression inside the radical sign).

then, you may take the fourth root of the result, note: in getting the fourth root of the variable, exponent must be divisible by 4, otherwise, it will be retain inside the radical sign.
