˝ = 1/x˛ + 1/y˛ +...+ 1/z˛

All variables must be different, positive integers, and there must be a finite number of terms.

e.g.: Excellent job. For those who might be skeptical, I offer the following.

The product of your numbers is P=5832x10^10 the square of which is then P^2=34012224x10^20. Summing P^2 divided by the square of each of your numbers does give exactly P^2/2:

(8503056 + 3779136 + 2125764 + 1360488.96 + 944784 + 236196 + 37791.36 + 13604.8896 + 3401.2224 + 1511.6544 + 377.9136)x10^20 = 17006112x10^20.
