Properties of The Challenge
Extracting the 13th root has certain properties. One is that the 13th root of a number is much smaller: a 13th root will have approximately 1/13th the number of digits. Thus, the 13th root of a 100-digit number only has 8 digits and the 13th root of a 200-digit number will have 16 digits. Furthermore, the last digit of the 13th root is always the same as the last digit of the power.
For the 13th root of a 100-digit number there are 7,992,563 possibilities, in the range 41,246,264 – 49,238,826. This is considered a relatively easy calculation. There are 393,544,396,177,593 possibilities, in the range 2,030,917,620,904,736 – 2,424,462,017,082,328, for the 13th root of a 200-digit number. This is considered a difficult calculation.

“I always draw a parallel between oppression by the regime and oppression by men. To me it is just the same. I always challenge men on why they react to oppression by the regime, but then they do exactly the same things to women that they criticize the regime for.”
—Sethembile N., South African black anti-apartheid activist. As quoted in Lives of Courage, ch. 19, by Diana E. H. Russell (1989)
