WHAT SHE DID ???

There aren’t invalid integers x , and z such as :  xn + yn = zn  as soon as n is an integer strictly upper to 2.

In case n = 1, the equation xn + yn = zn corresponds to the usual addition.

In case n = 2, this equation has another infinity of not invalid solutions, the smallest of which is (3, 4, 5)  :   32 + 42 = 52
