Multiply under the radicals and get



Break it into the quotient of two fifth roots:



The power of y in the denominator must be a
multiple of 5, so it needs to be multiplied by
y4 so that it will become y10.

So we multiply the entire fraction by 




We multiply under the radicals:



The denominator is simplified by dividing the exponent 10
by the index of the root 5, getting exponent 2, and 
eliminating the radical,  so we have




Now we will simplify the numerator.
Write 32 as 25
Write x7 as x5x2




Finally you can take the two fifth powers out
of the fifth root and have 2x in front of the
radical:
