comment Limit of $\sqrt[x]{\frac{\tan x}{x}}$ as $x \to 0$
Using your method, what is $\left(\frac{\tan x}{x}\right)^\frac{1}{x^2}$ for $x \to 0$?

comment Limit of $\sqrt[x]{\frac{\tan x}{x}}$ as $x \to 0$
The power in my first example is $1/x$, in my second it's $1/x^2$. None of theam head to zero for $x \to 0$.

@DavidMitra: Using your argument, $(\tan x / x)^{1/x^2}$ should go to $1$ for $x \to 0$ as well. But it's $\sqrt[3]{e}$. See wolframalpha.com/input/…

revised Limit of $\sqrt[x]{\frac{\tan x}{x}}$ as $x \to 0$
Replaced $\cos$ by $\sin$, because wrong. Does not change the results.
