I know from my using my calculator that the answer to cube root 3 * cube root 3 is 2.08....
But I'm wondering if there's a method for multiplying two cube roots where the radicand is the same in each, something similar to the method for multiplying square roots where the radicand is the same, e,g;
sqrt 2 * sqrt 2 = sqrt 4 (which = 2)
or,
sqrt 12 * sqrt 12 = sqrt 144 (which = 12)
Is there such a method? Like;
cube root y * cube root y = cube root z ?

Perhaps you mean as:
cube root y * cube root y * cube root y = cube root y^3
For example:
cube root 27 * cube root 27 * cube root 27 = cube root 19683 (which = 27)

Thanks, guys; very satisyfing
And, I'm guessing, the same for 4th root, 5th root etc?
E.g,
4th root 16 * 4th root 16 * 4th root 16 * 4th root 16 = 4th root 16^4 = 16
(2) . (2) . (2) . (2) = 16
