I think you want to write a root in exponential form, it goes like this:

Here is the equation.  I'm trying to display the results using a rational exponent instead of the radical

What do you want to see as the result?  This?

Yes. I would like to see the result as you have shown.

Thanks

Mathcad automatically changes the notation only when the expressions are very large. Evidently  for smaller expressions there is nothing to do, even if we write it in exponential form, mathcad rewrites it in a rational form.

Or did you want:

(Because:

The first part in getting rational results is that you have to write your equation WITHOUT floating point numbers, so in you example case like:

Or am I misunderstanding your question?

Succes!

I don't think it's possible to force Mathcad's symbolics to show this format.

Ok. Thanks for your help.

Given the right Mathcad (11):

I would say, this comes very close.

Unfortunately the 0 before .25 cannot be forced.

On the other hand, to get 250.0 when the exponent is 0.5, but 250 when the exponent is 1/2, while the original expression contains 250.0 is extremely difficult.
