Super thanks in advance to anyone who could help.

the Math.pow() function in Java takes two doubles as its arguments (which means they can be fractions). A property of exponentiation is that powers which are fractions are equivalent to nthroots. Therefore cube roots are equivalent to raising a number to the (1/3) power.
Hope this helps.

ME is restricted to 1.3 and the Math library has been around since 1.0
So we'd need to see your snippet to determine why "it's not working".

And what do you mean by "not working?" Does it not compile? Or is it not giving you the desired result?

use Math.cbrt() function
for more functions in math class, go to http://java.sun.com/...4/tt1102.html#1

when i said it's not working, i mean it doesn't compile.
Math.cbrt(x) and Math.pow(x,y) functions are not included in the package in Java ME. it is very limited compared to java SE.
Can you help me extract the cube root of numbers? any other idea?
i really need this function for the mobile application that i am working with.

Google cube root algorithm
or if you are really really lazy
Google cube root algorithm java

Or if you are incredibly lazy and don't even want to Google: http://today.java.ne...powmethod.html
