Question

利用计算器求下的各式的值，从中你能发现什么规律？

5.49的立方根 54.9的立方根 549的立方根 5490的立方根 54900的立方根 549000的立方根 谢谢好心人了

Answer 1

5.49^(1/3) = 1.7641037161163
54.9^(1/3) = 3.8006462428151
549^(1/3) = 8.1882441100602
5490^(1/3) = 17.641037161163
54900^(1/3) = 38.006462428151
........
规律是每一项与前一项的比等于后一项和他的比值 5.49的立方根/54.9的立方根=54.9的立方根=549的立方根=549的立方根/5490的立方根=5490的立方根/54900的立方根 =54900的立方根/549000的立方根

Answer 2
