Answer:
The answer would be -15/4
Step-by-step explanation:

This is the answer because it is in its simplest form
Since the 2 and x^1/4 are multiplying we can do the math separately and then just multiply them afterwards
2^-4 is the same as 1/(2^4) which is 1/16
(x^1/4)^-4 (POWER RULES REVIEW)
2 exponents of same base you just add (basically multiply the two)
so x^(1/4x-4) = x^(-1)
which is just 1/x
so the answer is 1/16x
