(1-1/2-1/4-1/8-1/16-1/32)÷64 简便计算开头要{1-(1/2-1/4)-几分之一(忘了抄是几分之一,各位看看应该填几吧)-1/4)···}×64
(1-1/2-1/4-1/8-1/16-1/32)÷64
=[1-(1-1/2)-(1/2-1/4)-(1/4-1/8)-(1/8-1/16)-(1/16-1/32)]÷64
=(1-1+1/2-1/2+1/4-1/4+1/8-1/8+1/16-1/16+1/32)÷64
=1/32×1/64
=1/2048
(1-1/2-1/4-1/8-1/16-1/32)×64
=[1-(1-1/2)-(1/2-1/4)-(1/4-1/8)-(1/8-1/16)-(1/16-1/32)]×64
=(1-1+1/2-1/2+1/4-1/4+1/8-1/8+1/16-1/16+1/32)×64
=1/32×64
=2

[1-(1/2-1/4)-(1/4-1/8)-(1/8-1/16)-(1/16-1/32)*64=[1/2-1/32]*64=15/32*64=30
