for that U can use Math.pow(a,b) funcn directly //availble in java 👉Math.pow(a,2); //a^2 ... square 👉Math.pow (a,1.0/3.0); //a^(1/3) ... cuberoot 👉Math.pow (a,1.0/2.0) //a^1/2 ... square root of a //can also be written as Math.sqrt(a); //in above example ... it will be 👉👉 int b=(int)Math.pow(8,1.0/3.0); //remember value comes out as double ... so we neex to typecast it to int type

It's known as cube root: https://www.tutorialspoint.com/java/lang/math_cbrt.htm "The java.lang.Math.cbrt(double a) returns the cube root of a double value"

In English, we say square root for n^(1/2) and cube root for n^(1/3). n^(1/4) is known as quad root or fourth root. All other roots are known as fifth, sixth, seventh, eighth root etc.
