Hi, 

Please, excuse me if I let you notice that the first exponent is 0.3 + 2 * 5 * x ^ 0.1 and not 0.3 + 2.5 * x ^ 0.1.

Hi,

 

that is 0.3 + 2 * 5 * x ^ 0.1 

 

0.3 + 10 * x ^0.1

There are several ways to solve this, see attached.

Your guess value is way off.

I suppose the error message hints at that.

 

Success!

Your guess value is way off.

I suppose the error message hints at that.


The error message simply states "This variable is undefined" and tracing back does not help (we don't even get the usual "no solution found" when we do).

But you are correct that the low guess value is causing the error. The guess must be at least  37 or higher for Mathcad to be able to find a solution.

 

But if I understand the last reply of the OP correct he tried to tell us that he mistakenly wrote 2*5 were he should have written 2.5 (as JXB already had assumed).
