Geometric means iin Raster Calculator

[HollyMorris]

Hello:

I am trying to enter a few formulas in the raster calculator using geometric means but I am having difficulty.  For instance, one formula is:  (a^2 * b) ^ 1/3

I've tried using the EXP function and manually entering the value (1/3) after EXP and before the () but it has not worked.  Does anyone have a suggestion on how to solve this problem?

For anyone who wants to know, I solved my issue.

The formula would best be represented by ((a**2)*b)**(1.0/3.0)
