I meant line 2 (it's actually a joke the math professors on the writing team of the Simpsons put in there: it doesn't disprove Fermat's Theorem, but most calculators at the time didn't have the accuracy to cumpute that directly, which is kind of the joke)
No, but you just discovered a hidden nerd-bait joke from the show's creators. One of the guys working on the show created some sort of program that could generate close-but-not-quite solutions. The one shown here isn't actually equal, but they are close enough that the difference won't show up without a more precise calculator, since both sides are roughly 6.397665635 x 1043.
