German theorem of Sophie

The theorem of Sophie Germain states the following property:

For entire naturalness n strictly larger than 1,

n^4 + 4~

is not first.

More generally, the mathematician establishes the following equality:

n^4 + 4 m^4 = (n^2 + 2 m^2 + 2 mn) (n^2 + 2 m^2 - 2 mn) ~

One also calls theorem of Sophie Germain the following result:

Either \, p a prime number such as \, 2p+1 or also a prime number. Then, there do not exist nonnull entireties x, \, there, \, z, and not multiples of \, p, such as \, x^p + y^p = z^p (in other words, the first case of (large) the theorem of Fermat is true for such exhibitors).
