Answer:
16x^(4/5)
----------------
x
Step-by-step explanation:
While you don't specifically state what you're supposed to do with this expression, it's an easy guess that you want to rationalize the denominator.
Let's write it as
16
------------ . We want to eliminate the radical from the denominator.
x^(1/5)
To accomplish this, multiply numerator and denominator by x^(4/5). Note that [x^(1/5)][x^(4/5)] = x^1 = x, which is what we want for the new denominator.
We end up with:
16x^(4/5)
----------------
x
