Homework Help: Nice limit

  1. Oct 30, 2005 #1
    Hi all,

    could you help me how to solve this limit?

    \lim_{x \rightarrow \infty} \left( 1 + 10^{-x}\right)^\left(10^x\right)

    Common adjustments for log involving the limit log (1)/0 don't work and no other idea comes to my mind...

    Thank you for any help.

    Look at the problem again, it looks incredibly like:
    [tex]\lim_{x \rightarrow \infty} \left( 1 + \frac{1}{x} \right) ^ x = e[/tex]
    Can you go from here?
    Viet Dao,
