I assume the problem is to rationalize
If this is correct, then the denominator of fraction needs to be a perfect square. Since a variable raised to an even power is a perfect square, the current denominator, y^5, is not a perfect square. The simplest way to make the exponent on y even is to multiply y^5 by y which results in y^6.
The only valid way to multiply the denominator by y is to multiply the numerator by y, also:
which results in:
Now you can split the square root of the fraction into a fraction of square roots:
, will simplify to y^3 making the answer:
