找规律,并计算.1-1/2=1/2,1/2-1/4=1/4.1/8-116=1/16,用这规律计算:
(1)1-1/2-1/4-1/8-1/16 (2)1-1/2-1/4-1/8-1/16-1/32-1/64 (3)1/6-1/12-1/24-1/48-1/96
要有算式和答案.
答
1-1/2-1/4-1/8-1/16
=1/2-1/4-1/8-1/16
= 1/4-1/8-1/16
=1/16
1-1/2-1/4-1/8-1/16-1/32-1/64=1/64
1/6-1/12-1/24-1/48-1/96=1/6*1/16=1/96求算式第一个不是详细写了吗?全部详细1-1/2-1/4-1/8-1/16=1/2-1/4-1/8-1/16=1/4-1/8-1/16=1/8-1/16=1/161-1/2-1/4-1/8-1/16-1/32-1/64=1/2-1/4-1/8-1/16-1/32-1/64=1/4-1/8-1/16-1/32-1/64=1/8-1/16-1/32-1/64=1/16-1/32-1/64=1/32-1/64=1/641/6-1/12-1/24-1/48-1/96=1/12-1/24-1/48-1/96=1/24-1/48-1/96=1/48-1/96=1/96
