I'm stumped

Question about the task

Resolved

It seems my code performs all the requirements, but it is failing still. It says I need to use cube to implement the ninthDegree method. And I am doing that, yet it does not pass. And my code is correct it does not show but i did:

public static long ninthDegree(long a) {
        long b = cube(a) * cube(a) * cube(a);
        return b;

You won't blow any minds by unveiling a calculator that can raise a number to the power of three.
But a calculator that can raise a number to the power of nine is another matter! So let's implement one!

To do this, create a public static long ninthDegree(long) method.
It must take a long integer value as an argument.
The method should raise the passed value to the ninth power and return it as the method's result.
You'll remember from your high school math class that you can get the ninth power of a number if you raise it to the third power and then raise the result to the third power. Let's use this rule in our program.
In the ninthDegree() method, raise the passed argument to the third power using the cube() method.
Then pass the result to the cube() method once again. The final result is the method's return value.

Requirements:

There must be a public static long ninthDegree(long a) method.
The ninthDegree() method must return the result of raising the passed number to the power of nine.
The ninthDegree() method must use the cube() method to successively cube the number.

package en.codegym.task.pro.task06.task0609; /* A cubed cube calculator */ public class Solution { public static void main(String[] args) { } public static long cube(long a) { return a * a * a; } //write your code here public static long ninthDegree(long a) { long b = cube(a) * cube(a); return b; } }

Have you already tried what they ask? 'Then pass the result to the cube() method once again. The final result is the method's return value.' So I assume CG wants to see something like that: return cube(cube(a)); or long temp = cube(a); return cube(temp);
