WebNov 29, 2015 · does the proof of Fermat's Theorem somehow rely on the fact that $\sqrt[3]{2}$ is irrational? Edit Added: Even if $\sqrt[3]{2}$ is irrational was contained in FLT, it would have had to be proven by some means, so as long as FLT did not assume FLT then it doesn't matter that a specific instance of FLT was contained in proof of FLT FLT being … WebInfinite Descent is a method of proof which utilizes the extremal principle to contradict the extremality of an extreme object. This principle is best described using an example: Problem 1. Prove that is irrational. Proof. Assume otherwise that is rational; that is, =, where p and q are positive integers. Squaring both sides gives , and .
In mathematics, a proof by infinite descent, also known as Fermat's method of descent, is a particular kind of proof by contradiction used to show that a statement cannot possibly hold for any number, by showing that if the statement were to hold for a number, then the same would be true for a smaller number, leading to an infinite descent and ultimately a contradiction.
