e^(e^x) = 2
Date: 01/28/2002 at 00:40:52 From: elizabeth grayson Subject: e I have been fruitlessly trying to solve e^(e^x) = 2. Help!
Date: 01/28/2002 at 12:22:35 From: Doctor Paul Subject: Re: e Take the ln of both sides to obtain: e^x * ln(e) = ln(2) but ln(e) = 1 so we have e^x = ln(2) repeat the process to obtain: x = ln(ln(2)) I hope this helps. Please write back if you'd like to talk about this some more. - Doctor Paul, The Math Forum http://mathforum.org/dr.math/
