what i mean is the namubers that when the result of multiplying them together is the same as adding them:

How Long Will My Generator Run?
Hurricane Irene just wandered up the east coast and once again my house was spared from any significant problems. We lost power for about 11 hours, but that was nothing compared to my neighbors, many
of whom were without power for days. Luckily, I have a 12 KW whole-house generator.

product of n-1 commutators
I'm probably missing something very simple here, but I can't figure this one out.
Let $x_{1},...,x_{n}$ be elements in a group $G$.
show that an element of the form $x_{1}x_{2}...x_{n}x_{1}^{-1}x... | {"url":"http://mathhelpforum.com/advanced-algebra/165953-product-n-1-commutators.html","timestamp":"2014-04-20T10:05:56Z","content_type":null,"content_length":"39098","record_id":"<urn:uuid:d96c0dda-b27f-424f-bac3-62c59deb40b0>","cc-path":"CC-MAIN-2014-15/segments/1397609538110.1/warc/CC-MAIN-20140416005218-00041-ip-10... |

Portable wind turbine
1. Unfortunately there is virtually no agreement among the major wind turbine manufacturers, let alone independent designers such as these, as to where the power rating comes from. I can safely say,

Surface Area of a Cylinder
To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r^2, where r is the radius
of the end. There are two ends so their combinded surface area is 2 π * r^2.
