... product ab is an element of µn ; that is, we want to prove that (ab)n = 1. We raise ab to the nth power and use the fact that multiplication in a field is commutative to get (ab)n = an bn . Since a ∈ µn , we know that an = 1; and since b ∈ µn , we know that bn = 1. Therefore, (ab)n = an bn = 1 · 1 = ...

... interior angle of 144 degrees. If the interior angle is 144, then the exterior angle is 180 – 144 = 36 degrees. Since 360 ÷ 10 = 36, a 10-sided polygon, or a decagon, has and exterior angle of 36 and thus an interior angle of 144 degrees. There are ten (10) sides on the regular polygon that is the ...
