Another method, but more keystrokes, at least on the 8-digit Canon LC-37: 27 √ √ √ √ √ √ √ √ √ √ √ - 1 / 3 + 1 = × = × = × = × = × = × = × = × = × = × = × = -> 3.000989 Replace 3 with 5 and you’ll get the 5th root: 1.9338459 From https://www.quora.com/Using-a-simple-cal...root-n-odd PS: Again, it looks like they have trouble with /th/ – “...den press √ (12 times)” :-) |
