# Limit of x^((x^x)-1) as x->0

• tsuwal
In summary, the conversation discusses finding the limit of x^((x^x)-1) as x approaches 0, which is an indeterminate form. The attempt at solving it involves using L'hopital's rule, but it is not a practical solution. An alternative approach is suggested, but it ultimately leads to the same limit and L'hopital's rule is still needed.

## Homework Statement

Limit of x^((x^x)-1) as x->0

Lim x^x=1
x->0

## The Attempt at a Solution

it's an 0^0 indetermination so I tried to solve it the usual way, by first calculating the limit of log(x)*(x^x-1) as x->0 with L'hopital's rule. I got e^0=1 confirmed by Wolfram. However, the using L'hopitals rule on this limit is not very practical, is there a better soluction?

Suppose you let y = x^((x^x)-1), what is ln(y) = ?

I would get the same limit log(x)*(x^x-1) as x->0 but solving this by L'hopital's rule takes a while or is it the fastest way?

Oh whoops, I read too quickly. Yeah I don't see how you would do this without LH otherwise.
