1-0.1-0.01-.-0.000000001
=1-(0.1-0.01-.-0.000000001)
=1-0.1*(1-0.000000001)/(1-0.1)
=1-(1-0.1^9)/9
=8/9-0.1^9/9

1-0.1-0.01-0.001-0.0001-……-0.000000001怎么算
1减0.1减0.01减0.001减0.0001
1-0.1-0.01-0.001-.-0.000000001巧算半小时内高分!
水表*1*0.1*0.01*0.001*1000*100*10
1里有几个0.1,几个0.01,几个0.001
1里面个( )0.01( )个0.001是0.1
1除以0.1除以0.01除以0.001除以…除以0.(00…10个0)01
-40,-20,-10,1,0.1,0.01,0.01,0.001,0.0001,0.00001有什么规律
0.1/0.01*0.001/0.0001 如何简便
0.1+0.01+0.001+0.0001+.=2009/()
0.1+0.01+0.001+0.0001无限循环等于多少? 我没学过极限1-0.1-0.01-0.001循环又等于多少
0.1分之1-0.01分之1-0.001分之1-0.0001分之1
1/0.1-1/0.01-1/0.001-1/0.0001.=?怎么算?
这水表是多少度?0*1000 2*100 8.5*10 8*1 8.5*0.1 4*0.01 4.5*0.001 8.5*0.0001 这个到底是多少度水?
1里面有100个()填空题:1、0.1 2、0.01 3、0.001
用数学归纳法证明0.1+0.01+0.001+.+0.1的n次方=((1-0.1的n次方)/9)
