Question #e772c

Answer 1

I agree with Welder and also I add that I was not able to find an easy way out to this one! Probably there is an easy way to solve it but I didn't find it.

What I tried was to use a "Brute Force" approach...
Basically, I tried values of `x` in `e^x+x` until I got the result, `5`!
I also cheated because I used Excel to do it for me!!!

As you can see, I built a table in Excel trying to get the required value:

In the first column are listed values of `x` I've chosen to get as near as possible to `5` starting from `1.30654` and incrementing it by `0.000001`. In the second column you have the corresponding results calculated from `e^x+x`.
The best result was reached for: `x=1.306559`

Well, I hope it helps...
