First of all, we must remember that what distinguishes these types of problems from other ones is that they have repeated factors. Basically, all you do is count up, which means, as you separate the initial fraction, you repeat the factors, but with their exponent increasing incrementally by 1. It sounds confusing, but if you had saw an example, you'd get it right away. As always, with these types of lengthy problems, you must remember to calculate carefully, as one mistake could ruin you. Oh, and you can't use calculators for many of these problems, since most of the answers come out as decimals, which we are not permitted to utilize, unless they are definite (don't go on forever). Fin.
