(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

is e^x^2 = 4 equivalent to e^x = 2

2. Relevant equations

As above

3. The attempt at a solution

This is just an exercise, but I'm quite stuck as how to show this is true (or false for that matter). I thought to take the log of both sides and use the log identity to get rid of the double exponent and cancel out the 'ln e' (=1):

ln e^x^2 = ln 4

x^2 ln e = ln 4

x^2 = ln 4

but I'm not sure this helps me (kinda went around in a circle!), nor am I clear on another method to use. I'm sure there's a log property I'm missing? :S
