Rationalize the denominator. Assume all variables represent positive numbers?
 245x3
y5

Online "^" is used to indicate an exponent. Your presentation is unclear.
245 * x^3/y^5?
245x^3 * y^5?
(245x^3)/y^5?
Since this is not my area of expertise, I searched Google under the key words "unsaturated alkenes" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
