如有不明白,
1/2,1/4,
(1+1/2)(1+1/2^2)(1+1/2^4)(1+1/2^8)+1/2^15
1,2,4,4,1,()
200*(1-1/2)*(1-1/3)*(1-1/4)*.*(1-1/100)
(1+1/2)(1+1/2^2)(1+1/2^4)(1+1/2^8)+1/2^15=?
(1+1/2)(1+1/2^2)(1+1/2^4)^(1+1/2^32)
1,2,4,4,1,( )
(1-1/2)(1-1/3)(1-1/4).(1-1/100)
1.(1+1/2+1/3+1/4)*(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4)=2.(1+1/2+1/3+1/4+1/5)*(1/2+1/3+1/4+1/5+1/6)-(1+1/2+1/3+1/4+1/5+1/6)*(1/2+1/3+1/4+1/5)=
计算 ( 1+1/2)*(1-1/3)*(1+1/4)*(1-1/5)*.*(1+1/1000)*(1-1/1001)
(1-2/1)*(1-3/1)*(1-4/1)*.*(1-2007/1)*(1-2008/1)
求和:1+(1+2)+(1+2+4)+(1+2+4+6)+(1+2+4+.2^n-1)
(1+1/2)(1+1/4)(1+1/16)(1+1/256) 等于多少?快
(1+1/2)(1+1/4)(1+1/16)(1+1/256) 等于多少?
(1-1/2)×(1-1/3)×(1-1/4)……×(1-1/2008)计算方法
1、1/2、1/4、1/7
