One interesting thing about roots is that for a fractional root (such as the 1.5th root), there will actually be more than n answers (2 in the case of the 1.5th root), but some of the roots will count less because they assume the root of a number to be a specific thing (for the 1.5th roots, one assumes the positive sqrt of the number and one assumes the negative sqrt, making them both count as half a 1.5th root).
