Sometimes it is needed to keep the powers as the fractional form. However Mathematica tends to write
How do I keep x^(1/2) as it is in the output without writing it as Sqrt[x]?
Here is a simple example:
expr = Rationalize[1+x^(0.5),0.0000001] >> output.m
1 + Sqrt[x]
Instead I want the output to have the form
1 + x^(1/2)
I could not find any solution for this.
