+%28%28c%5E2%2Bd%29%2F%28d%5E3c%5E2%29%29%2F%28c%5E4%2Bd%5E4%29+
Make the denominator an improper fraction by placing it over 1
+%28%28c%5E2%2Bd%29%2F%28d%5E3c%5E2%29%29%2F%28%28c%5E4%2Bd%5E4%29%2F1%29+
There is a rule :
+%28a%2Fb%29%2F%28c%2Fd%29+=+ad%2Fbc+
Apply it
+%281%28c%5E2%2Bd%29%29%2F%28%28d%5E3c%5E2%29%28c%5E4%2Bd%5E4%29%29+
Since nothing else can be factored ... you are done.
