5d85bf67 3a7e 4c81 A95c 07154cef2e50 Is there a formal proof for $( 1) \\times ( 1) = 1$? it's a fundamental formula not only in arithmetic but also in the whole of math. is there a proof for it or is it just assumed?. The theorem that $\binom {n} {k} = \frac {n!} {k! (n k)!}$ already assumes $0!$ is defined to be $1$. otherwise this would be restricted to $0

The reason why $1^\infty$ is indeterminate, is because what it really means intuitively is an approximation of the type $ (\sim 1)^ {\rm large \, number}$. and while $1$ to a large power is 1, a number very close to 1 to a large power can be anything. Possible duplicate: how do i convince someone that $1 1=2$ may not necessarily be true? i once read that some mathematicians provided a very length proof of $1 1=2$. can you think of some way to. There are infinitely many possible values for $1^i$, corresponding to different branches of the complex logarithm. the confusing point here is that the formula $1^x = 1$ is not part of the definition of complex exponentiation, although it is an immediate consequence of the definition of natural number exponentiation. 如何在输入法里输入这个符号？google了很多发现都不对.
