2010-3|2-5|4-9|8-17|16-33|32-65|64-129|128-257|256
2010-3|2-5|4-9|8-17|16-33|32-65|64-129|128-257|256
=2010-8-(1/2+1/4+1/8+1/16+1/32+1/64+1/128+1/256)
=2010-8-(1-1/256)
=2010-8-1+1/256
=2001又1/256
再问: 1/2+1/4+1/8+1/16+1/32+1/64+1/128+1/256为什么=1-1/256
再答: 1/2+1/4=3/4=1-1/4 1/2+1/4+1/8=7/8=1-1/8 1/2+1/4+1/8+1/16=15/16=1-1/16 1/2+1/4+1/8+1/16+1/32=31/32=1-1/32 1/2+1/4+1/8+1/16+1/32+1/64=63/64=1-1/64 1/2+1/4+1/8+1/16+1/32+1/64+1/128=127/128=1-1/128 1/2+1/4+1/8+1/16+1/32+1/64+1/128+1/256为什么=1-1/256
