很高兴为您解答,skyhunter002为您答疑解惑
如果本题有什么不明白可以追问,
1+101+101-101
(1/100-1)*(1/101-1)*.*(1/2013-1)=?
1/100*101+1/101+102+1/n1/100*101+1/101+102+…+1/n(n+1)
计算:|100/1-99/1|+|101/1-100/1|-|101/1-99/1|
|1/100-1/99|+|1/101-1/100|-|1/101-1/99|
|1/101-1/99|-|1/100-1/99|-|1/100-1/101|=_____
|1/101-1/99|-|1/100-1/99|-|1/100-1/101|等于多少?
|1/101-1/99|-|1/100-1/99|-|1/100-1/101|
|1/101-1/100|+|1/102-1/101|-|1/102-1/100|=?
|1/101-1/99|-|1/100-1/99|-|1/100-1/101|,
1+1/2-1/2+...+1/100-1/101
1/1*2+1/2*3+1/3*4+...+1/100*101+1/101*102
计算|1/100-1/99|+|1/101-1/100|-|1/101-1/99|计算 | 1/100 - 1/99 | + | 1/101 - 1/100 | - | 1/101 - 1/99 |(像1/100、1/99都是分数来的)
|1/100-1/99|+|1/101-1/100|-|1/100-1/99|=?
(-1+1/100)*(-1+1/101)*(-1+1/102)*.*(-1+1/2010)=?
计算(-1+1/100)×(-1+1/101)×(-1+1、102)×……×(-1+1/2008)
(1-1/100)×(1-1/101)×(1-1/102)×...×(1-1/2008)=?
(-1+1/100)*(-1+1/101)*(-1+1/102)*...*(-1+1/2007)的解
