N'agbanyeghị usoro dị mfe nke Fermat's Last Theorem n'ogo nke mgbakọ ụlọ akwụkwọ dị mfe, ọchụchọ maka akaebe ya were ihe karịrị afọ 350. Emere nke a site n'aka ndị ọkachamara mgbakọ na mwepụ na ndị amateur, nke mere e ji kwenye na theorem bụ onye ndu n'ọtụtụ ihe akaebe na-ezighi ezi. N'ihi ya, onye Bekee na American mathematician Andrew John Wiles ghọrọ onye jisiri ike gosipụta ya. Nke a mere na 1994, e bipụtara nsonaazụ ya na 1995.
Laa azụ na narị afọ nke XNUMX, mgbalị ịchọta ihe akaebe maka n = 3 Ọ bụ Abu Mahmud Hamid ibn al-Khizr al-Khojandi, onye Tajik mathematician na onye na-enyocha mbara igwe mere ya. Otú ọ dị, ọrụ ya adịghị adị ruo taa.
Fermat n'onwe ya gosipụtara theorem naanị maka n = 4, nke na-ewelite ajụjụ ụfọdụ banyere ma o nwere ihe àmà n'ozuzu ya.
Nakwa ihe akaebe nke theorem maka iche iche n tụrụ aro ndị ọkachamara mgbakọ na mwepụ ndị a:
- n'ihi na n = 3People: Leonhard Euler (Swiss, German and mathematician and mechanic) in 1770;
- n'ihi na n = 5Ndị mmadụ: Johann Peter Gustav Lejeune Dirichlet (ọkà mmụta mgbakọ na mwepụ German) na Adrien Marie Legendre (ọkà mmụta mgbakọ na mwepụ France) na 1825;
- n'ihi na n = 7: Gabriel Lame (onye na-ahụ maka mgbakọ na mwepụ nke France, mekaniki, ọkà mmụta sayensị na injinia);
- niile dị mfe n <100 (ma ewezuga primes oge 37, 59, 67): Ernst Eduard Kummer (onye mgbakọ na mwepụ German).
