6.求平方根表和立方根表

举下例子

7.1~20立方根表

立方根 3√0 = 0 3√1 = 1 3√2 = 1.25992104989487 3√3 = 1.44224957030741 3√4 = 1.5874010519682 3√5 = 1.7099759466767 3√6 = 1.81712059283214 3√7 = 1.91293118277239 3√8 = 2 3√9 = 2.0800838230519 3√10 = 2.15443469003188 3√11 = 2.22398009056932 3√12 = 2.28942848510666 3√13 = 2.35133468772076 3√14 = 2.41014226417523 3√15 = 2.46621207433047 3√16 = 2.51984209978975 3√17 = 2.57128159065824 3√18 = 2.6207413942089 3√19 = 2.66840164872194 3√20 = 2.71441761659491 3√21 = 2.75892417638112 3√22 = 2.80203933065539 3√23 = 2.84386697985157 3√24 = 2.88449914061482 3√25 = 2.92401773821287 3√26 = 2.96249606840737 3√27 = 3

8.我需要常用平方根和立方根表，常用的就行
