0 Posted 10 Mar 2013 according to a rule which states that,In case of equal amounts, if the bases are equal then the powers are equal too!! 1^1= 1^2 Thus: 1=2 0 Share this post Link to post Share on other sites

0 Posted 10 Mar 2013 according to a rule which states that,In case of equal amounts, if the bases are equal then the powers are equal too!!1^1= 1^2Thus: 1=2 Very nice wolfgang. Definitely honorable mention. But the OP asks to add a symbol and a well-known proof. I think this implies something about taking logarithms with base 1.Is the well-known mathematical symbol i ?I mean,square root of -1? Krishna, no, sorry that is not what I had in mind. 0 Share this post Link to post Share on other sites

It is a beginner-level bit of mathematical magic to prove that 1=2.

This demonstration probably occurs multiple times in the history of this forum.

Its fallacy depends on embedding, and cleverly hiding somewhere in the "analysis," a division by zero.

Which of course is not permitted. So regarding this matter our world is still a safe abode.

Nonetheless, this equality still has a life for puzzle solvers.

By the application of a familiar proof, the addition of a single well-known mathematical symbol,

and without resorting to prohibited mathematical operations, 1=2 can still be shown to be true.

Have fun, and please use spoilers.
