raster calculator syntax error

[ReşatAkgöz]

Hi;
I'm trying to create soil erosion risk map with rusle method.
I would like to calculate rainfall erosivity factor with this formula
((((( [Dem_10m] / [Dem_10m]) * 604) + (([Dem_10m] - 1135) * 0.17)) / 393).Pow( 1.75 )) * 52.32

when I write this formula at raster calculator, give syntax error. can error be from (pow)?
I'm using 9.3
anyone have any idea?
thank you for your helps !

that pow syntax is for Arcview 3.x, check the help for your version of arcmap, ie for 9.3
