Reformatted so that the Latex expressions work.

I am trying to calculate a very simple expression with the Prime:

\( \frac{\sqrt{3}*\sqrt[3]{2*x}}{\sqrt[4]{3*x}} \)

I don't know how to write that without latex but the attachment is an image of the Prime display.

As you can see the answer is not very useful, actually it should simply be:

\( \sqrt[4]{432*x} \)


\( 2^{1/3}*3^{1/4}*x^{1/12} \)

If I try to simplify the prime goes in a loop...

What do I have to do to obtain the correct answer?

Thank you very much


Are you sure?

If I define:




And evaluate both of them at 1, I get 1.65814935214 and 4.55901411391 respectively.
