Pierre de Fermat was a French lawyer who practiced mathematics as an amateur. He was famous for challenging some of the greatest mathematical minds of his time to solve problems that he created. Generally considered one of the key pioneers in analytical geometry, probability, and optics. However, he may be most famous for a note he left in the margin of a book where he claimed that a^n+ b^n does not equal c^nFor any power over 2. Fermat's Last Theorem confounded mathematicians for centuries because they could not provide it to be correct or incorrect. In the year 1994; approximately 300 years after he posed the statement a mathematician from Princeton was about to prove that it was correct for all values n > 2. A textbook from 1980 might describe the problem as which of the following?a) Decidable, because a solution was certain but had not been written down yet.b) Decidable, 200 years had offered time for some numbers to be tested correct.c) Undecidable, no algorithm had been determined to work for all inputs.d) Undecidable, computers were too simple to test many cases at the time
