Answer 1

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
