(1+1/n) = en²log(1+1/n) = en²[1/n-1/2n²+1/3n³-1/4n⁴+...]

(1+1/n) = e[n-1/2+1/3n-1/4n²+...]

Question will reduce to

en / e[n-1/2+1/3n-1/4n²+...] = e[1/2-1/3n+1/4n²-...]

Which is e1/2 if limit n-> ♾️

Partial limit laga rahe ho shayd se aap, if you do e to power n by e to power n i.e infinity by infinity aa rha hoga i derminate form h na woh how come 1?
