Is there a way to prevent Mathematica from simplifying numbers under the root?

Consider the following example:

a = 48^(1/3)

The standard output will be:

2 * 6^(1/3)

But what I want it to remain as it is for the output:


Here is more elaborate example:

Ldot := Vvap/Sv
Lstar = ((48 \[Eta])/(\[Rho] g Sv) Ldot)^(1/3)

What I want is to simplify everything, except (48)^(1/3). For example:

 Lstar // FullSimplify // TraditionalForm


enter image description here

Which is good except the fact that I want (48)^(1/3) to remain as it is.


You can use


for display purposes. But this expression cannot be calculated with. The right solution depends on what you actually want to achieve.

There is also Inactive/Inactivate, which can be calculated with in some cases.
