I have this number:

84586075770624998147441974158189380700174460760744963832062282657

I generated it using this:

16515489654164894**4 + 10046498489496563**4

so its not square root (power of 2). Its power of 4.

Question: Its possible to compute which power of 4 form my original number and get back orig number? Its possible to do that using power of 2, but what about power of 4?

sqrt(84586075770624998147441974158189380700174460760744963832062282657, 4 = 17053939551218935.1675822943023889

do you mean this? this is the 4th root of your gigantic number using web 2.0 calculator and the \(\sqrt[y]{x}\) button...... put in 'x' push the button then enter 'y' ans =

If you expect the fourth root of your large number to be an integer you are doomed to disappointment - search "Fermat's last theorem".

Not exactly. Its possible to compute square of 2 (269916694664582966990754893514409**2 + 108309988975954046249057727301124**2) , but why it´s not possible to compute higher (such as 4)? It works for 2, so it must also work with 4.

MathKing, you are not only doomed to disappointment, you are just doomed.

**Not all is lost:** If you and Mr. BB have one of your “intellectual” conversations, then maybe Ginger will write some more hilarious satire.

The expectation for finding an exception to Fermat’s Last Theorem is zero. The proof for that is almost 30 years old. Ginger comments on it here: https://web2.0calc.com/questions/help_79263#r8

As for the expectation that Ginger will write more satire, it probably depends on how your conversation with Mr. BB unfolds. The one you had a year ago was new and obviously inspiring. However, Ginger is very talented. She often can make silk purses from sow’s ears: it’s worth a shot
