[nckrzan]

Hi,

I have problem in my Macro,
one of the necessary mathematical operations is 3th root of the number
however I really don't know how to present those function in the ImageJ
macro.
Can You help me?

Marcel,

I assume you need the 3rd root of an image.  This would be

run("Log");
run("Divide...", "value=3.000");
run("Exp");


If you need a function that computes the third root of number, it might be

print("The third root of 27 is "+thridRoot(27));

function thridRoot(x){
        return exp(log(x)/3);
}
