What is the expected way to show the work on this? IIRC (long time ago), the method I learned for computing cube roots involved knowing the cubes of single digit numbers (e.g. 3^3 = 27, being one of them).
- vkou 10y agoPresumably, it consists of verifying that 3 x 3 x 3 = 27. But who the hell knows. Alternatively, maybe it expects a binary search through the decision space? 2 x 2 x 2 = 8 < 27. Too bad this breaks down when the problem is trivially adjusted - not in the X^3 = 28 way (As binary search can approximate that), but in the X^3.3 = 27 way.
