Fermat’s Last Theorem
Published:
In school, we learn about the Pythagorean theorem, which is used to compute the length of any one side of a right triangle given the other two sides. We can formally express the Pythagorean theorem as \(a^2 + b^2 = c^2\), where a, b, c are the lengths of the sides of the triangle and c represents the hypotenuse.
If we generalize the formula for different powers, we get \(a^n + b^n = c^n\). Unlike the Pythagorean theorem, this generalized equation does not have three definite (non-zero) integer values for a, b, and c when \(n\) is greater than 2. This is known as Fermat’s Last Theorem, which was later proved by other mathematicians.
