问题描述:
|1/101-1/99| - |1/100 - 1/99| - |1/100 -1/101|等于多少?
要有说明哦!
答
原式=1/101-1/100-1/100+1/101
=2*(1/101-1/100)
=2*[(100-101)/(100*101)]
=2*(-1/10100)
=-2/10100
答
原始=(1/99-1/101)-(1/99-1/100)-(1/100-1/101)=1/99-1/101-1/99+1/100-1/100+1/101=0
答
|1/101-1/99| - |1/100 - 1/99| - |1/100 -1/101|
=1/99-1/101-1/99+1/100-1/100+1/101
=0.
@@@
1/99>1/100>1/101.
答
=1/99-1/101-1/99+1/100=1/100+1/101
=0
