I would have replied to the older thread but it seems that is not possible, so I will have to post my question here.(adsbygoogle = window.adsbygoogle || []).push({});

https://www.physicsforums.com/threads/slide-rule.245855/

@BobG mentioned being able to solve a particular problem:

exp(x)=x^4

really quickly using a slide rule. He emphasized how easy it is but I've searched all around the Internet, having used a Versalog slide rule for years, and while I can solve exp(x)=x^3 iteratively using the cube scale, I do not know the quick trick to solving for one power higher.

Maybe it is obvious and I am missing it. Could anyone help me out here?
