I'm not sure what you mean.
+sqrt%28%28441x%5E2+%2Ay%5E7%29%2F%28529x%5E6%29%29+
You can start by reducing the fraction by dividing out the x%5E2 with the x%5E6.
+sqrt%28%28441+%2Ay%5E7%29%2F%28529x%5E4%29%29+
If this is the case, then notice that everything here is a perfect square since 21%5E2+=+441and +23%5E2+=+529, except the x%5E7.
Break down the y%5E7+ into +y%5E6%2Ay.
Now:
+sqrt%28%28441+%2Ay%5E6%29%2F%28529x%5E4%29%29%2A+sqrt%28y%29+
%28%2821y%5E3%29%2F%2823x%5E2%29%29%2Asqrt%28y%29
