    2. Relevant equations

    I know the answer is e but i forgat how to do the lny=xln(1+1/n) and then I solve an get an e because ln and e are inverse but i forgot the process can you please show me the process

    at the stage

    [tex] \stackrel{lim}{n \rightarrow \infty}, ln(y) = n.ln(1+1/n) [/tex]

    the limit is indeterminant 0 * infinity, so can you re-write it and use L'Hopitals rule...?
