hey anyone please can tell me this one:
A=lim(e^(1/n*logn)) (n tends to 0)
i took log on both sides and then by using l hospital rule
i arrive at lim(-1/n) (n tends to 0)
can't solve further...please help

$$\lim_{x\to 0^+}\frac{\log x}{x}=-\infty\Longrightarrow \lim_{n\to 0}e^{\frac{\log n}{n}}=\lim_{x\to -\infty}e^x=0$$

Another way:

$$e^{\frac{\log n}{n}}=\left(e^{\log n}\right)^{1/n}=n^{1/n}\xrightarrow [n\to 0]{} 0$$

Of course, we assume in the above that \,n\, is a continuous variable.

hey the problem is

e^(1/(n*logn)) log n is with n

log n is not in numerator

Yeat...too bad you didn't write parentheses in the OP to make that clear, uh?
 


This belongs in the homework forum and should contain an effort from the OP. Locked.
